A survey of 225 students showed the mean number of hours spent studying per week was 20.6 and the standard deviation was 2.7. assuming a 90% confidence level, the margin of error is approximately
Answer:
Assuming a 90% confidence level, the margin of error is approximately
0.3
Which of the following gives the confidence interval?
between 20.3 and 20.9
Explanation:
A survey of 225 students showed the mean number of hours spent studying per week was 20.6 and the standard deviation was 2.7, the margin of error is approximately 0.2948.
What is standard deviation?Standard deviation is a statistical measure that describes the amount of variation or dispersion of a set of data values.
It measures the average amount of deviation of each data point from the mean (or average) of the entire dataset.
To find the margin of error for a sample mean, we use the formula:
Margin of error = z * (standard deviation / sqrt(sample size))
where z is the z-score corresponding to the desired confidence level. For a 90% confidence level, the z-score is 1.645 (we can look this up on a standard normal distribution table).
Plugging in the values given in the problem:
Margin of error = 1.645 * (2.7 / sqrt(225))
= 1.645 * (2.7 / 15)
= 0.2948 (rounded to four decimal places)
Therefore, the margin of error is approximately 0.2948.

Pat needs to determine the height of a tree before cutting it down to be sure that it will not fall on a nearby fence. the angle of elevation of the tree from one position on a flat path from the tree is and from a second position farther along this path it is what is the height of the tree?
The height of the tree, which Pat needs to determine, before cutting it down to be sure that it will not fall on a nearby fence is 111 ft.
What is right angle triangle property?In a right angle triangle, the ratio of the opposite side to the base side is equal to the tangent angle between them.
[tex]\tan\theta=\dfrac{b}{a}[/tex]
Here, (b) is the opposite side, (a) is the base side.
Pat needs to determine the height of a tree before cutting it down to be sure that it will not fall on a nearby fence.
The angle of elevation of the tree from one position on a flat path from the tree is
[tex]H=40^o[/tex]
From a second position,
[tex]I=60\rm\; ft[/tex]
Farther along this path it is,
[tex]b=30^o[/tex]
Let the distance between tree and first position is x. Thus, from the trigonometry,
[tex]\tan 40=\dfrac{h}{x}\\h=x\tan 40[/tex] ....1
The distance between tree and second position is (x+60) ft. Thus, again from the trigonometry,
[tex]\tan 30=\dfrac{h}{x+60}\\h=(x+60)\tan 40[/tex] ......2
Compare the equation 1 and 2,
[tex]x\tan (40)=(x+60)\tan 30\\0.839x=0.577x+34.64\\0.839x-0.577x=34.64\\x=\dfrac{34.64}{0.262}\\x=132.25\rm\; ft[/tex]
Put this value in equation 1 as,
[tex]h=(132.25)\times \tan40\\h\approx111\rm\;ft[/tex]
Thus, the height of the tree, which Pat needs to determine, before cutting it down to be sure that it will not fall on a nearby fence is 111 ft.

What is a Cartesian equation?A Cartesian equation for a curve is one that is only expressed in terms of x and y.
To find the Cartesian equation for the curve
Since, [tex]\rm cos^2 \theta =2cos2\;\theta - 1[/tex], then

So the Cartesian curve is x² - y² = 1, which is a hyperbola having the lines y= ±x as asymptotes.

Decide if the following sentence is grammatically correct or incorrect. está bien por ahora. correct incorrect
Answer:
That is correct
está bien por ahora is grammatically correct.
What is Grammar?
A natural language's grammar is a system of structural rules that limit how sentences, phrases, and words can be put together by speakers or writers.
The phrase can also be used to describe the study of such restrictions, a subject area that covers phonology, morphology, and syntax as well as the frequently added fields of phonetics, semantics, and pragmatics. Traditional grammar and theoretical grammar are the two methods now used to study grammar.
These limitations, the bulk of which - at least in the case of one's native language(s) - are acquired not by conscious study or instruction but rather by hearing other speakers, have successfully been internalized by fluent speakers of a linguistic variation or lect.
Therefore, está bien por ahora is grammatically correct.

Manny is using a computer model to investigate the effects of substitution mutations. The model presents manny with a long base sequence for a gene. Manny then selects one base for a mutation, such as by substituting cytosine, "c", for adenine, "a". Manny completes many trials of mutations. In most trials, the result of the substitution mutation is either no effect, or a polypeptide in which one amino acid is altered. In one trial, however, the result is a truncated polypeptide. Many of its terminal amino acids are missing. What is the most likely explanation for the truncated polypeptide
The truncated polypeptide results in the computer simulations performed by Manny can be found with the alteration in the gene structure and the formation of the stop codon in between the chain sequence.
What is truncated polypeptide?The truncated polypeptide is the sequence of the amino acid that is modified in a way to enable the formation of the tertiary and the quaternary structure of the protein.
The truncation in the polypeptide chain can be attained with the alteration in the gene structure. The attempts of Manny to perform the substitution mutation may result in the change in the cytosine nucleotide at the C or the N terminal of the polypeptide chain.
This results in the formation of the termination in the elongation with the stop codon, and thereby forms the truncated polypeptide.

Explanation:
Researchers are studying two different designs of computer keyboards, j and k, to investigate the effectiveness of the design on the speed of data entry. The researchers believe there is a tendency for people entering data with keyboard j to have faster entry times compared with people entering data with keyboard k. Using the same set of data for entry, the researchers randomly assigned 5 people to keyboard j and 6 people to keyboard k and recorded the number of seconds each person took to enter the data. The following dotplots show the observed entry times for the two keyboards
The data from the people using the j and the k keyboards reveal that it is not appropriate to conduct the two-sample statistical t-test, as there was the presence of outliers.
What is a two-sample t-test?It is a statistical test that is used in the determination of the equality of the two mean populations. The test is used for the analysis of the statistical difference between the two tests.

How much energy is required to vaporize 41. 4 g of dichloromethane (ch 2cl 2) at its boiling point, if its δh vap is 31. 6 kj/mol?
Answer: 15.4 kJ
Explanation:
Molar mass of CH2Cl2,
MM = 1*MM(C) + 2*MM(H) + 2*MM(Cl)
= 1*12.01 + 2*1.008 + 2*35.45
= 84.926 g/mol
Mass(CH2Cl2) = 41.4 g
Use:
number of mol of CH2Cl2,
n = mass of CH2Cl2/molar mass of CH2Cl2
= (41.4 g)/(84.93 g/mol)
= 0.4875 mol
Given:
ΔH = 31.6 KJ/mol
= 31600 J/mol
Use:
Q = ΔH * number of mol
= 31.6 KJ/mol * 0.4875 mol
= 15.4 KJ
Therefore, it takes 15.4 kJ of energy to vaporize 41. 4 g of CH₂Cl₂ at its boiling point
