A large university is interested in learning about the average time it takes
students to drive to campus. The university sampled 287 students and
asked each to provide the amount of time they spent traveling to
campus. This variable, travel time, was then used conduct a test of
hypothesis. The goal was to determine if the average travel time of all
the university's students differed from 20 minutes. Suppose the
large-sample test statistic was calculated to be z = 2.67. Find the p-value
for this test of hypothesis.
