7. Trading volume on the New York Stock Exchange is heaviest during the first half hour (early morning) and last half hour (late afternoon) of the trading day. The early morning trading volumes (millions of shares) for 13 days in January and February are shown here (Barron’s, January 23, 2006; February 13, 2006; and February 27, 2006). 214 163 265 194 180 202 198 212 201 174 171 211 211 The probability distribution of trading volume is approximately normal. a) Compute the mean and standard deviation to use as estimates of the population mean and standard deviation. b) What is the probability that, on a randomly selected day, the early morning trading volume will be less than 180 million shares? c) What is the probability that, on a randomly selected day, the early morning trading volume will exceed 230 million shares?
Answers
In this problem, first we find the sample mean and the standard deviation, and then, we use the normal distribution. Then, we get that:
a) The mean is of 199.69 and the standard deviation is of 25.02.
b) 0.2148 = 21.48% probability that, on a randomly selected day, the early morning trading volume will be less than 180 million shares.
c) 0.1131 = 11.31% probability that, on a randomly selected day, the early morning trading volume will exceed 230 million shares.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.Item a:
The mean is the sum of all observations divided by the number of observations, thus:
[tex]\mu = \frac{214 + 163 + 265 + 194 + 180 + 202 + 198 + 212 + 201 + 174 + 171 + 211 + 211}{13} = 199.69[/tex]
The standard deviation is given by the square root of the sum of the difference squared between each observation and the mean, divided by the number of values. Thus:
[tex]\sigma = \sqrt{\frac{(214-199.69)^2 + (163-199.69)^2 + (265-199.69)^2 + (194-199.69)^2 + ... + (211-199.69)^2}{13}} = 25.02[/tex]
The mean is of 199.69 and the standard deviation is of 25.02.
Item b:
This probability is the p-value of Z when X = 180, thus:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{180 - 199.69}{25.02}[/tex]
[tex]Z = -0.79[/tex]
[tex]Z = -0.79[/tex] has a p-value of 0.2148.
0.2148 = 21.48% probability that, on a randomly selected day, the early morning trading volume will be less than 180 million shares.
Item c:
This probability is 1 subtracted by the p-value of Z when X = 230, thus:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{230 - 199.69}{25.02}[/tex]
[tex]Z = 1.21[/tex]
[tex]Z = 1.21[/tex] has a p-value of 0.8869.
1 - 0.8869 = 0.1131
0.1131 = 11.31% probability that, on a randomly selected day, the early morning trading volume will exceed 230 million shares.

Add all the numbers in the data set, and divide its sum by the number of items in the set:
Mean = [tex]\frac{2+9+10+12+12}{5}[/tex] = [tex]\frac{45}{5}[/tex] = 9

Answers
Answer:
The center of the circle is at: C=(−2,3).
The radius of the circle is r=5.
Step-by-step explanation:
A circle with center at (h,k) and a radius of r has equation (x−h)2+(y−k)2=r2.
In this example our circle equation can be written as:
(x−(−2))2+(y−3)2=(5)2
So, we have: h=−2 , k=3 and r=5.

what is the purpose of using measures of variability?
Answers
Answer: it gives you descriptive statistics that summarize your data.
Human population numbers are in constant flux. Suppose a country has a population of 20 million people at the start of one year and during the year there are 600,000 births, 350,000 deaths, 100,000 immigrants, and 5,000 emigrants. You and your classmates will determine the total population at the end of the year and then model expected change over a longer period.
Answers
According to the question given,
[tex]\sf\longmapsto \: emigrants=-5000[/tex]
[tex]\sf\longmapsto \: Immigrants = 100000[/tex]
[tex]\sf\longmapsto \: Death -350000[/tex]
[tex] \sf \longmapsto \: Birth=600000[/tex]
Now let's solve out and get the result!
The change of population:
[tex] \sf \longmapsto600000-350000 + 100000 - 5000=350000[/tex]
The total population at the end of the year:
[tex]\sf\longmapsto \:2000000 + 350000 [/tex]
[tex]\sf\dashrightarrow2350000[/tex]
Hence the total population at the end of the year is 2350000.At the end of the year, the population will be 20,345,000.
The rate of change in population is 1.75%.
What is rate?Rate is a measurement to determine the change in one quantity with respect to another quantity.
The given information are,
Total population of the country initially = 20,000,000
Total number of births during the year = 600,000
Total number of deaths during the year = 350,000
Number of immigrants = 100,000
And number of emigrants = 5,000
The population at the end of the year
= 20,000,000 + 600,000 - 350,000 + 100,000 - 5,000
= 20,345,000
At the end of the year the population will be 20,345,000.
The increase in population = 20,345,000 - 20,000,000
= 345,000
the rate of increasing = 345000/20000000)x100 = 1.75%
The rate of change per year is 1.75%.
