Question

Determine if the data from each question would be better suited for a hypothesis test on a mean or a hypothesis test on a proportion. If the data is suitable for a hypothesis test on a mean, type "M.", otherwise typemiddot"P" for a hypothesis test on a proportion. a) Do you believe Trump would make a good president? answer: ____ b) Did you vote in the last state primary? answer: ___ c) How many times have you voted in a presidential election in your lifetime? answer ___ d) Would you still vote if it cost you one dollar to do so? answer: ___ e) How old were you when you first voted in a presidential election? answer:

Explanation / Answer

a) Here the responses will be either yes or no. So there are to possible outcomes, either good or not good. So we have to test whether the proportion of good responses is more than not good responses. So it is a hypothesis test on a proportion and the answer is P. (Ans).

b) Here the responses will be yes if the person voted or no if he/she didn't vote. So we have to test the proportion of people voted in the last test primary against some certain value of proportion. So it is a hypothesis test on a proportion and the answer is P. (Ans).

c) Here the responses will be different numbers and we should test whether the mean of those numbers equals to some certain value of mean. So it is a hypothesis test on a mean and the answer is M. (Ans).

d) Here the responses will be yes if the personwill vote or no if he/she will not vote. So we have to test the proportion of people who will vote if it costs one dollar against some certain value of proportion. So it is a hypothesis test on a proportion and the answer is P. (Ans).

e) Here the responses will be different numbers (ages) and we should test whether the mean of those numbers (ages) equals to some certain value of mean. So it is a hypothesis test on a mean and the answer is M. (Ans).
