Andrew wishes to survey 50 randomly chosen students to try to disprove the claim that the percentage of students who are obese falls above a certain proportion.

Andrew found that the critical value for significance level of 5% corresponded to a proportion of 0.07 of students being obese. To assist in Andrew’s conclusions, you randomly picked 50 students and found that only 3 were obese.

Does your findings lend support to Andrew’s objective at 5% significance level? Justify your answer.
