Solve the problem.A small private college is interested in determining the percentage of its students who live off campus and drive to class. Specifically, it was desired to determine if less than 20% of their current students live off campus and drive to class. Suppose a sample of 108 students produced a test statistic of z = -1.35. Find the p-value for the test of interest to the college.

For the given value of α and observed significance level (p-value), indicate whether the null hypothesis would be rejected.α = 0.05, p-value = 0.10
