Test the professor's claim that the majority of students are in favour of more private
health-care options available at the 5% level of significance.
a. Compute the value of the test statistic and its corresponding p-value.
Enter 0 for both if cannot use normal approximation to binomial.
b. Conclude whether to reject the null hypothesis or not based on the p-value.
O Reject
O Fail to Reject
o Cannot Use Normal Approximation to Binomial
