reject the null hypothesis that p=0.6 B. We can reject the null hypothesis that p=0.6 and accept that p<0.6 (3) Test H0:p=0.6 against Ha:p≠0.6 Use α=0.01 test statistic z= positive critical zz score negative critical zz score The final conclusion is A. There is not sufficient evidence to reject the null hypothesis that p=0.6 B. We can reject the null hypothesis that p=0.6 and accept that p≠0.6
A random sample of 140 observations is selected from a binomial population with unknown probability of success pp. The computed value of p^ is 0.69
(1) Test H0:p=0.65 against Ha:p>0.65 Use α=0.01
test statistic z=
critical zz score
The final conclusion is
A. 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=0.6 against Ha:p<0.6 Use α=0.05
test statistic z=
critical zz score
The final conclusion is
A. There is not sufficient evidence to reject the null hypothesis that p=0.6
B. We can reject the null hypothesis that p=0.6 and accept that p<0.6
(3) Test H0:p=0.6 against Ha:p≠0.6 Use α=0.01
test statistic z=
positive critical zz score
negative critical zz score
The final conclusion is
A. There is not sufficient evidence to reject the null hypothesis that p=0.6
B. We can reject the null hypothesis that p=0.6 and accept that p≠0.6
