Question
In a study to estimate the proportion of residents in a certain city and its suburbs who
favor the construction of a nuclear power plant, it is found that 77 of 125 urban residents
favor the construction while only 56 of 100 suburban residents are in favor. Is there a
significant difference between the proportions of urban and suburban residents who
favor construction of the nuclear plant? Make use of a P-value.

Past experience indicates that the time required for high school seniors to complete a
standardized test is a normal random variable with a standard deviation of 7 minutes.
Test the hypothesis that = 7 against the alternative that o<7 if a random sample of the
test times of 18 high school seniors has a standard deviation s = 5.83. Use a 0.10 level
of significance.
