Every semester, I would like for more than 75% of my students to score a 70 or higher on the first test. This semester, out of the 72 students who took the first test, 59 got at least a C (scored higher a 70 or higher). Is there sufficient evidence to conclude, at the 10% significance level, that more than 75% of the students got at least a C on the first exam? Find the null and alternative hypotheses, test statistic, critical value(s) and critical region or p-value, as indicated, and state the final conclusion that addresses the problem. Show all seven steps.
