In a random sample of 110 voters, the proportion of voters in favor of a bond issue is 0.8. Let p = proportion of all voters who are in favor of the bond issue.(1) Test H0:p≤0.65 against H1:p>0.65. Use α=0.05.
The test statistic is
The critical value isThe final conclustion isA.There is not sufficient evidence to reject the null hypothesis that p≤0.65.B.We can reject the null hypothesis that p≤0.65 and accept that p>0.65.(2) Test H0:p≥0.5 against H1:p<0.5. use="" α="">
The critical value isThe final conclustion isA.There is not sufficient evidence to reject the null hypothesis that p≥0.5.B.We can reject the null hypothesis that p≥0.5 and accept that p<>(3) Test H0:p=0.55 against H1:p≠0.55. Use α=0.01.
The positive critical value is
The negative critical value isThe final conclustion isA.We can reject the null hypothesis that p=0.55 and accept that p≠0.55.B.There is not sufficient evidence to reject the null hypothesis that p=0.55.
