Topic: Hypothesis testing 140. Failure to meet payments on student loans guaranteed by the US government has been a
major problem for both banks and the government. Approximately 50% of all student loans
guaranteed by the government are in default. A random sample of 350 loans to college
students in one region of the US indicates that 147 are in default. Calculate the pvalue
associated with the test statistic.

Topic: Hypothesis testing 142. A survey of the wine market has shown that the preferred wine for 17% of Americans is
merlot. A wine producer in California where merlot is produced believes the figure is higher
in California. She contacts a random sample of 550 California residents and asks which wine
they purchase most often. Suppose 115 replied that merlot was the primary wine. Calculate
the appropriate test statistic to test the hypotheses.
