Refer to Exercises 11 and 13. Suppose that the sample proportion of students who did all their assigned homework last week is p̂ = 57/100 = 0.57. Would this sample proportion provide convincing evidence that less than 60% of all students at the school completed all their assigned homework last week? Explain your reasoning.

Exercises 11 and 13.

A school newspaper article claims that 60% of the students at a large high school completed their assigned homework last week. Assume that this claim is true for the 2000 students at the school.

Some skeptical AP® Statistics students want to investigate the newspaper’s claim in Exercise 11, so they choose an SRS of 100 students from the school to interview.

In their sample, 45 students completed their homework last week. Does this provide convincing evidence that less than 60% of all students at the school completed their assigned homework last week?
