What is the probability of obtaining a z-score greater than one SD above the mean?
z ≥ 1
The correct answer is The probability of obtaining a z-score greater than one standard deviation (SD) above the mean can be calculated using the standard normal distribution table or a statistical software.
Assuming a normal distribution, the probability of obtaining a z-score greater than or equal to 1 is approximately 0.1587, which means there is a 15.87% chance of obtaining a z-score greater than one SD above the mean. This can be explained by the properties of a normal distribution, where 68% of the data falls within one standard deviation of the mean, and the remaining 32% is distributed in the tails of the distribution. Half of this 32% (16%) is located in the upper tail of the distribution, which corresponds to z-scores greater than one SD above the mean. Therefore, the probability of obtaining a z-score greater than one SD above the mean is 0.1587 or approximately 15.87%.

Molly is wrapping up parts of sandwich’s to sell at her sandwich cart.she cuts each sandwich in fourths and then wraps each fourth separately.she says that she wrapped 16 fourths,so she wrapped 16 whole sandwich’s. What was mollys mistake?
Molly's mistake is that she actually wrapped 4 whole sandwiches, not 16.
Since she cuts each sandwich into fourths, each whole sandwich produces four fourths. Therefore, if she wrapped 16 fourths, she must have cut up and wrapped 16/4 = 4 whole sandwiches.
It seems like Molly made the mistake of assuming that the number of fourths wrapped was equivalent to the number of whole sandwiches wrapped. However, this is only true if she were wrapping the entire sandwich and not just the fourths.
in a right triangle , the leg lengths are 4 in and 4.5 in. what is the length of the hypotenuse?
Answer: [tex]c = \frac{\sqrt{145} }{2}[/tex]
Explanation:
The formula for the hypothenuse is [tex]c^{2} = a^{2} +b^{2}[/tex]
In this case a = 4in and b = 4.5in
therefore [tex]c =\sqrt{(4.5in)^{2} +(4in)^{2} }[/tex]

Here is a dilemma for our class. It illuminates the value of and the issues surrounding utilitarianism.
You are a United States Senator. You represent your home state. The House of Representatives has sent the Senate a bill that will make college education free for any American who wants one. It is now up to the Senate to pass it and send it to the president to be signed into law. You are also a businessperson, and like most others in America, you paid for your own education with loans. The arguments for the benefits of an education without debt are pretty obvious.
Reducing indebtedness
Strengthening the economy by producing a more educated workforce
Providing opportunities for those of limited financial means
At the same time, there are some reasons against it too.
Asking taxpayers to subsidize something that doesn't directly benefit them
Not addressing the underlying cause of high college tuition and possibly encouraging colleges to raise tuition rates
Providing a benefit that the wealthy and upper-middle class don't need
As a senator, you must do your research (and cite it) to understand the numbers involved (e.g., potential number of students who will benefit, potential dollars in tax burden for individuals and businesses, and potential number of ex-students who've paid off or are paying off their student loan debt).
The majority rules here, so you must be extra careful, as a utilitarian, not to abuse that power. You are looking out for the most happiness for the most people, regardless of any personal or procedural beliefs.
How would a utilitarian senator vote on this dilemma? Why?
How would the views of the people of the state you represent influence your vote? In other words, if the majority were in favor, would you vote in favor of it too?
Would a Kantian vote differently than a utilitarian? Why or why not?
A utilitarian senator would vote in favor of the bill that makes college education free for any American who wants one. The senator's decision would be based on the potential benefits of reducing indebtedness, strengthening the economy by producing a more educated workforce, and providing opportunities for those of limited financial means.
What is the explanation for the above response?The senator would also take into account the potential tax burden on individuals and businesses. The senator would prioritize the overall happiness and well-being of the majority of the American people over any personal or procedural beliefs.
The views of the people of the state the senator represents would certainly influence their vote. If the majority of the people in the senator's state were in favor of the bill, the senator would likely vote in favor of it as well.
A Kantian senator may vote differently than a utilitarian senator. Kantian ethics prioritize duty, obligation, and universal moral principles, rather than the consequences of actions. A Kantian may consider whether the bill violates any moral principles or whether it respects the autonomy and dignity of individuals. They may also consider whether it is fair to ask taxpayers to subsidize something that doesn't directly benefit them. However, the decision would ultimately depend on the individual Kantian's interpretation of moral principles.

Dottie Kleman is the ""Cookie Lady."" She bakes and sells cookies at 50 different locations in the Philadelphia area. Ms. Kleman is concerned about absenteeism among her workers. The information below reports the number of days absent for a sample of 10 workers during the last two-week pay period. 4 1 2 2 1 2 2 1 0 3 1. Determine the mean and the standard deviation of the sample. 2. Develop a 95 percent confidence interval for the population mean. 3. Is it reasonable to conclude that the typical worker does not miss any days during a pay period?
The mean of the sample is:
(4 + 1 + 2 + 2 + 1 + 2 + 2 + 1 + 0 + 3 + 1) / 11 = 1.64
To find the standard deviation of the sample, we first need to calculate the variance:
((4 - 1.64)² + (1 - 1.64)² + (2 - 1.64)² + (2 - 1.64)² + (1 - 1.64)^² + (2 - 1.64)² + (2 - 1.64)² + (1 - 1.64)² + (0 - 1.64)² + (3 - 1.64)² + (1 - 1.64)²) / 10
= 1.1144
So the standard deviation of the sample is the square root of the variance:
√(1.1144) = 1.055
To develop a 95 percent confidence interval for the population mean, we first need to calculate the standard error of the mean:
1.055 / √(11) = 0.318
Then, we can use the t-distribution with 10 degrees of freedom (n-1) and a 95% confidence level to find the margin of error:
t(0.025, 10) * 0.318 = 0.677
The 95% confidence interval is then:
1.64 - 0.677 to 1.64 + 0.677
or
0.963 to 2.317
It is not reasonable to conclude that the typical worker does not miss any days during a pay period, as the sample mean is 1.64, indicating that on average, workers miss almost 2 days per pay period. However, the confidence interval does include the possibility of 0 days absent, so we cannot rule out the possibility entirely.

Three cards are drawn from a standard deck of cards and not replaced.
What is the probability that the first card is a King and the last two cards are Queens? Write your answer as a simplified fraction.
Are the events independent? Explain.
The probability that the first card is a King and the last two cards are Queens when three cards are drawn from a standard deck without replacement is 1/5525, and the events are not independent.
What is a deck of cards?
A deck of cards is a collection of 52 rectangular-shaped cards, usually made of paper or plastic, that are used to play various card games. The deck is divided into four suits (clubs, diamonds, hearts, and spades), with each suit containing 13 cards (Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, and King). In some card games, such as poker, the Ace can be used as a high or low card, depending on the rules of the game. The deck of cards also includes two Jokers, which are often used as wild cards in certain games.
The probability of drawing a King on the first card is 4/52 (since there are 4 Kings in a deck of 52 cards).
After the first King is drawn, there are 51 cards remaining, of which 4 are Queens. So the probability of drawing a Queen on the second card is 4/51.
After the second Queen is drawn, there are 50 cards remaining, of which 3 are Queens. So the probability of drawing a Queen on the third card is 3/50.
To find the probability of all three events happening together, we multiply the probabilities of each event:
(4/52) * (4/51) * (3/50) = 1/5525
Therefore, the probability that the first card is a King and the last two cards are Queens is 1/5525.
The events of drawing the King and the Queens are not independent because the probability of drawing the Queens depends on whether or not a King was drawn first. If a King was drawn first, then there are fewer cards left in the deck, which changes the probability of drawing a Queen on the second and third cards.
