Suppose now the researcher is interested in the proportion of students in the class who are in a business program.

Compute a point estimate of the population proportion.
A recent study reported that the proportion of students who enroll in the class that are in a business program (or plan to be) is at least 60%. Conduct a hypothesis test, at a significance level of 3%, to refute this researcher’s claim. Please use the p-value approach. (explicitly list and perform the steps in this procedure).
