Use the data to calculate the sample variance, s2. (Round your answer to five decimal places.)
n = 7:
1.5, 3.4, 1.9, 1.9, 3.2, 2.9, 3.0
s2 =
Construct a 95% confidence interval for the population variance, σ2. (Round your answers to two decimal places.)

A transportation researcher wants to determine if male or female
commuters use different forms of transportation. Sample
data is as follows:
Single Driver Carpool Bus or Train Bicycle Total
Men 200 50 25 50 325
Women 150 175 25 25 375
Total 350 225 50 75 700
Perform a hypothesis test at 95% confidence, to determine whether
transportation choice is independent of gender. To get
full credit state your null and alternate hypothesis, your test
statistic, show your p-value, and state your conclusion: are
transportation choices independent of gender? YES or NO

3. Many economists use the ideas embedded in the circular flow to describe their understanding of the capitalist market economy. Using the circular flow’s concepts explain what has to happen in order for there to be a full employment level of equilibrium income achieved. What does the full employment level of income imply about the economy’s operation? You can draw the circular flow if that will help you answer the question, but you don’t have to draw it.
4. Keynes created the economic concept of the multiplier. While it may seem like magic, it’s not. Explain why the idea of a multiplier is important in macroeconomics and how it works.

You are at a sports complex that has several events going on to
include soccer, lacrosse, basketball and football. as you walk
around and stop at the different games you spot different incidents
occur that require the player t leave the field. these include a
player holding there arm/shoulder, one unable to put weight on
their foot/leg, one holding the area around the buttocks/upper
thigh, one is holding the side of his head, and one is holding
these stomach/side. knowing what you know now about the bones,
muscles and joints discuss in detail, what bones muscles or joints
are in these areas and what type of diagnostic technique could be
used

The 40-hour work week did not become a U.S. standard until 1940. Today, many white-collar employees work more than 45 hours per week because management demands longer hours or offers large monetary incentives. A random sample of 28 white-collar employees worked on average 46.80 hours per week. Is there any evidence that the true mean number of hours worked per week by white-collar employees is greater than 45? Assume that the population standard deviation is 3.04 hours. Please use the exact value (from R) for all critical values.
a) What assumptions are required so that you can perform a hypothesis tests and confidence interval for the mean hours worked per week?
b) Should you use a z distribution or a t distribution in this problem? Note that you will only get one try to get this question correct.
Please explain the correct choice.
c) Is there any evidence to suggest the true mean number of hours worked per week by white-collar workers is greater than 45? Perform the hypothesis test at a 0.7% significance level.
Calculate the test statistic.
Calculate the p-value. Please write your answer in scientific notation using an E for the exponent and including at least 3 decimal places. For example, 1.234 x 10-5 would be written as 1.234E-5
d) Calculate the appropriate 99.3% bound that is consistent with what you did in parts b) and c).
Interpret the bound calculated above.
e) In practical terms, do you think that the number of hours worked per week by white-collar workers is greater than 45? To receive credit, your answer must be more than just repeating the conclusions in parts c) and d). Please explain your answer. Hint: Difference and Effect Size.
f) Explain why parts c) and d) state the same thing. That is, what in part c) is consistent with what in part d)?
