(2) A random sample of 120 observations is selected from a binomial population with unknown probability of success p. The computed value of p is 0.63.
(1) Test Ho: p=0.65 against H:p> 0.65. Use a = 0.05.
test statistic z
critical z score
The final conclusion is
OA. We can reject the null hypothesis that p= 0.65 and accept that p > 0.65
OB. There is not sufficient evidence to reject the null hypothesis that p= 0.65
(2) Test Ho: p= 0.65 against H₁ : p < 0.65. Use a=0.01.
test statistic ===
critical score
The final conclusion is
OA. There is not sufficient evidence to reject the null hypothesis that p = 0.65
OB. We can reject the null hypothesis that p= 0.65 and accept that p < 0.65.
(3) Test Ho: p= 0.6 against Ha: P0.6. Use a = 0.05.
test statistic
positive critical score
negative critical score
The final conclusion is
A. There is not sufficient evidence to reject the null hypothesis that p=0.6.
OB. We can reject the null hypothesis that p=0.6 and accept that p / 0.6
