1. (5pt) In a recent New York City marathon, 25,221 men finished and 253 dropped out. Also,
12,883 women finished and 163 dropped out. We want to use a 0.01 significance level to test
the claim that the rate of those who finish is the same for men and women.

test statistic, critical value (or P-value) and conclusion)
b) Test the claim by constructing an appropriate confidence interval.
