The proportion of commuters on is purported to be 65%. A professor believes this to be inaccurate. He randomly selects 300 students on campus and determines 200 of them to be commuters. Can the professor reject the campus claim of 65%? Write the hypotheses for this scenario. Is this one tailed or two tailed? Why? What statistical test would be used for this scenario? Explain why.

Expert Solution
Step 1
1
Step 2
Determine the whether the test is one or two tailed.
From the information, given that the proportion of commuters on campus is purported equals 0.65 and the claim is whether the professor can reject the campus claim of 0.65 or not.
It is clear that the direction of the tail in the given problem not indicated with the single tail and it is necessary to find out whether the professor can reject the campus claim of 0.65 or not which clearly depicts that the given test is only two tailed.
Therefore, the test is of clearly two tailed.
