2. Answer these short questions below.
a. How might the auditor effectively use preliminary analytical procedures in the audit of various expense accounts, such as miscellaneous expenses? Give an example of how analytical procedures used in the audit of such accounts.
b. Explain why examining a sample of cash disbursements made after the end of the year is useful in determining the completeness of accounts payable.
c. The auditor often examines some expense accounts, such as legal expenses, in detail even if the account balance is not material. Explain why.
d. Why does the auditor examine travel and entertainment expenses? What would poor controls regarding executive reimbursements say about the tone at the top for purposes of evaluating and reporting on internal control?

A researcher conducts a survey of attitudes towards early prison release. She surveys 170 women and 200 men. She finds that 32% of women are in favor of early release., and 20% of men are in favor of early release. Conduct a statistical test to determine whether there is a difference in attitudes between women and men in their attitudes about early release. Use alpha= .05 to test the statistical hypothesis.
State the hypothesis in statistical terms:
What is the value of the test statistic?
State the obtained p-value:
Do you reject or fail to reject the null hypothesis:
Describe the conclusion of your test in non statistical terms:

Kidneys produce the hormone erythropoietin whenever more red blood cells are necessary. Think of reasons for the body needing more red blood cells.
Athletes who abuse erythropoietin many more red blood cells than usual. (Examine Figure 6.3 from Chapter 6). Explain why an athlete might die from having too many red blood cells.

Immediately after a ban on using hand-held cell phones while driving was implemented, compliance with the law was measured. A random sample of 1,250 drivers found that 98.9% were in compliance. A year after the implementation, compliance was again measured to see if compliance was the same (or not) as previously measured. A different random sample of 1,100 drivers found 96.9% compliance.
State an appropriate null and alternative hypothesis for testing whether or not there is any statistical difference (i.e., a two-sided test) in these two proportions measured initially and then one year later. Conduct the test of hypothesis using a significance level of α= 0.05. Be sure to check the assumptions and conditions for your test. State the P-value of your test and also state your conclusion. (Feel free to use R in showing your work - and show your commands and output if using R.)
Develop a 95% confidence interval for the true difference in proportions between the first survey and the second survey and explain what this confidence interval means in context of this problem. (Feel free to use R in showing your work - and show your commands and output if using R.

One variable that is measured by online homework systems is the amount of time a student spends on homework for each section of the text. The following is a summary of the number of minutes a student spends for each section of the text for the fall 2014 semester in a college statistics class at UHWO.
Q1 = 42 Q2 = 51.5 Q3 = 72.5

10) The sky looks blue because
The sky is reflecting the blue light from the ocean
The atmospheric particles scatter more of the blue light towards you than
the other colors
The atmospheric particles have absorbed all the other colors
Only blue light from the sun reaches Earth
11) Blue, green, red, and magenta light is projected onto a screen. We know that the green and blue light are horizontally polarized, and the red light is vertically polarized. If a student holds a polarizer up to the projector with its transmission axis along the vertical direction, what color will the magenta block appear?
Magenta
Red
Green
Blue
Black
12) When unpolarized light passes through a polarizing filter,
All the light passes through and is now polarized
About half the light passes through and remains unpolarized
About half the light passes through and is now polarized
It is completely absorbed by the filter

Recall the survey you took during the first week of class. One
of the questions was “do you agree
that it is inappropriate to speak on a cellphone while at a
restaurant?” Of the 1913 females that
responded to the survey, 1729 agreed with this statement. Of the
1276 males that responded to this
survey, 1111 agreed with this statement. Test to see if there is
any difference between males and
females with respect to how they feel about this issue. Use a
significance level of .05.
(a) State the appropriate null and alternative hypotheses.
(b) Calculate the test statistic and report the p-value.
(c) State your conclusion in context of the problem.
(d) Based only on the results of the hypothesis test, would you
expect a 95% confidence interval to
include 0? Explain.
(e) Calculate and interpret a 95% confidence interval for the difference between males and females.
2. In a recent baseball World Series, the Houston Astros were
ordered to keep the roof of their stadium
open. The Houston team claimed that this would make them lose a
home-field advantage, because
the noise from fans would be less effective. During the regular
season, Houston won 36 of 53 games
played with the roof closed, and they won 15 of 26 games played
with the roof open. Treat these
results as a simple random sample of games. Use a significance
level of 0.05 to test the claim that
the proportion of wins at home is higher with a closed roof than
with an open roof. Does the closed
roof appear to be an advantage?
(a) State the null and alternative hypotheses to determine whether
the closed roof is an advantage.
(b) The test statistic for the above test was z = 0.89 which
gives us a p-value of 0.1858. State a
conclusion in context of the problem.
(c) Based on the results of the hypothesis test, would you
expect a confidence interval to include
0. Why or why not?
3. In a study of the effects of marijuana use during pregnancy,
measurements on babies of mothers who
used marijuana during pregnancy were compared to measurements on
babies of mothers who did
not. A 95% confidence interval for the difference in mean head
circumference μ1 − μ2 (μ1 is mean
for mothers who don’t use marijuana and μ2 is the mean for mothers
who use marijuana) was 0.61
to 1.19 cm.
(a) Interpret this confidence interval in context of the
problem.
(b) Based on the confidence interval, what can we say about the
p-value of the following hypothesis
test: H0 : μ1 = μ2 versus H1 : μ1 > μ2 at the 0.05 significance
level? State your conclusion for
the test.

This format should allow you more time to think about your answer. The length of your answers should range from 2-4 paragraphs, depending on the complexity of the question. Remember to use the readings and your class notes to answer the questions. Use citations/quotes and then go on to interpret and explain the quote in your own words.
Feminist economists offer a different view of the economy by focusing attention on caring labor and the care economy. Why do they focus on care and what is meant by the care penalty? Finally, briefly explain some of the findings of empirical research on care work and the care penalty.
