Independent random samples were taken of male and female members
of University Entrepreneurship Club. These members were considering
starting a business. Of 500 members, 150 actually started a
business venture.
Estimate the value of the population proportion. (Round
your answers to 3 decimal places.)
Develop a 99% confidence interval for the population
proportion.

Researchers equipped random samples of 46 male and 58 female
students from a large university with a small device that secretly
records sound for a random 30 seconds during each 12.5-minute
period over two days. Then they counted the number of words spoken
by each subject during each recording period and, from this,
estimated how many words per day each subject speaks. The female
estimates had a mean of 16,177 words per day with a standard
deviation of 7520 words...

Independent random samples of sizes n1 = 307
and n2 = 309 were taken from two populations.
In the first sample, 92 of the individuals met a certain criteria
whereas in the second sample, 108 of the individuals met the same
criteria.
Test the null hypothesis H0:p1=p2versus the alternative
hypothesis HA:p1<p2.
a) Calculate the z test statistic, testing
the null hypothesis that the population proportions are equal.
Round your response to at least 3 decimal places.

Q2) Independent random samples of sizes n1 =
208 and n2 = 209 were taken from two
populations. In the first sample, 172 of the individuals met a
certain criteria whereas in the second sample, 181 of the
individuals met the same criteria.
Test the null hypothesis H0:p1=p2versus the alternative
hypothesis HA:p1>p2.
a) Calculate the z test statistic, testing the null
hypothesis that the population proportions are equal. Round
your response to at least 2 decimal places.

Independent simple random samples of 400 Hong Kong women and
380 Macao women were taken. Of Hong Kong women, 318 were found to
be in the labor force; of the Macao women, 276 were found to be in
the labor force. At the 5% significance level, do the data suggest
that the labor-force participation rate of Hong Kong women is
higher? Use the P-value approach to perform a hypothesis
test.

Random samples of female and male UVA undergraduates are asked
to estimate the number of alcoholic drinks that each consumes on a
typical weekend. The data is below:
Females (Population 1): 4, 5, 3, 6, 6, 4, 5, 3, 4, 2
Males (Population 2): 4, 6, 8, 4, 5, 6, 7, 6, 6, 7
Give a 95% confidence interval for the difference between mean
female and male drink consumption. For each confidence interval,
enter your answer in the form (LCL,...
