Suppose you conduct a test and your p-value is equal to 0.13. what can you conclude?

A) Reject the null hypothesis at alpha as 0.05 but not at alpha as 0.10.

B) Reject the null hypothesis at alpha as 0.05 but not at alpha as 0.01.

C) Reject the null hypothesis at alpha as 0.10 but not at alpha as 0.05.

D) Reject the null hypothesis at alpha as 0.01 but not at alpha as 0.05.

E) Reject the null hypothesis at alpha as 0.10, 0.05 and 0.01.

F) Do not reject the null hypothesis at alpha as 0.10, 0.05, and 0.01.

(1 point) Independent random samples, each containing 900 observations, were selected from two binomial populations. The samples from populations 1 and 2 produced 632 and 665 successes, respectively.

 

(a) Test against ≠ 0 . Use α = 0.07

Test statistic =

Rejection region lzl >

The final conclusion is

○ A. There is not sufficient evidence to reject the null hypothesis that  

○ B. We can reject the null hypothesis that and accept that ≠ 0 

 

(b) Test  against . Use α = 0.02

Test statistic =

Rejection region z >

The final conclusion is

○ A. There is not sufficient evidence to reject the null hypothesis that

○ B. We can reject the null hypothesis that and accept that  

 

(1 point) A random sample of 130 observations is selected from a binomial population with unknown probability of success p. The computer value of is 0.64.

    (1) Test : : p = 0.65 against : p > 0.65. Use α= 0.05.

test statistic z =

critical z score

The final conclusion is 

⭕ A. We can reject the null hypothesis that p = 0.65 and accept that p is > 0.65.

⭕ B. There is not sufficient evidence to reject the null hypothesis that p = 0.65.

    (2) Test : p = 0.5 against :p < 0.65. Use α = 0.01.

test statistic z =

critical z score

The final conclusion is 

⭕ A. We can reject the null hypothesis that p = 0.5 and accept that p is < 0.5.

⭕ B. There is not sufficient evidence to reject the null hypothesis that p = 0.5.

   (3) Test : p = 0.55 against : p ≠ 0.55. Use α = 0.01.

test statistic z =

positive critical z score
