The table below summarizes data from a survey of a sample of women. Using a 0.01 significance level, and assuming that the sample sizes of 900men and 300 women are predetermined, test the claim that the proportions of agree/disagree responses are the same for subjects interviewed by men and the subjects interviewed by women. Does it appear that the gender of the interviewer affected the responses of women?
| Man | Woman | |
| Women who agree | 617 | 235 |
| Women who disagree | 283 | 65 |
Identify the null and alternative hypotheses. Choose the correct answer below.
A.Upper H 0:The proportions of agree/disagree responses are different for the subjects interviewed by men and the subjects interviewed by women.
Upper H 1:The proportions are the same.
B.Upper H 0:The proportions of agree/disagree responses are the same for the subjects interviewed by men and the subjects interviewed by women.
Upper H 1: The proportions are different.
C.Upper H 0: The response of the subject and the gender of the subject are independent.
Upper H 1:The response of the subject and the gender of the subject are dependent.
Compute the test statistic.________

Using the simple random sample of weights of women from a data
set, we obtain these sample statistics: the sample size is 40 and
the sample mean was 151.83 pounds. Research from other sources
suggests that the population of weights of women has a standard
deviation of 30.43 pounds. Find the 90% confidence interval
estimate of the mean weight of all women.

Using the simple random sample of weights of women from a data
set, we obtain these sample statistics: n=50and xbar=140.23lb.
Research from other sources suggests that the population of weights
of women has a standard deviation given by σ=32.31 lb.
a. Find the best point estimate of the mean weight of all
women.
b. Find a 99 % confidence interval estimate of the mean weight
of all women.
