In a random sample of 140 voters, the proportion of voters in favor of a bond issue is 0.7. Let p = proportion of all voters who are in favor of the bond issue.(1) Test H0:p≤0.6 against H1:p>0.6. Use α=0.05.
The test statistic is:
The critical value is:The final conclustion isA.There is not sufficient evidence to reject the null hypothesis that p≤0.6.B.We can reject the null hypothesis that ?≤0.6p≤0.6 and accept that p>0.6.(2) Test H0:p≥0.6 against H1:p<0.6. use="" α="">0.6.>
The critical value is :The final conclustion isA.We can reject the null hypothesis that p≥0.6 and accept that p<>B.There is not sufficient evidence to reject the null hypothesis that p≥0.6.(3) Test ?H0:p=0.5 against H1:p≠0.5. Use α=0.05.
The positive critical value is :
The negative critical value is :The 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≠0.5.
