Explanation / Answer

Please post 1 question per post, as we are not allowed to answer assignment questions.

Q1.

Option 2 is the correct hypothesis.

This is because claim goes to the alternate hypothesis.

Please observe that this is a one tailed, right tailed test.

We have p = 16/29 = .552

P0 = population proportion = 1/2 = .50

Therefore, t = p-p0/ sqrt(p0*p0'/n) = (.552-.50)/sqrt(.5*.5/29) = .56

P value is p(t>.56) is .2887, which is got from t tables.

Hence, option 3 is correct.

Now, assuming .05 level of alpha we have pvalue of .2887 is more than .05 and hence we fail to reject null hypothesis.

Option 4 is wrong and 5 is correct.

Options 2 , 3 and 5 are correct.
