What is the decision at a 0.05 level of significance for each of the following t

Question

What is the decision at a 0.05 level of significance for each of the following tests? Hint: Find the critical value for each test; then make a decision. (Round your critical values to two decimal places.)

Part (a)

F(3, 29) = 2.96

Fcrit =  

Retain the null hypothesis.Reject the null hypothesis.   

Part (b)

F(5, 18) = 2.57

Fcrit =  

Retain the null hypothesis.Reject the null hypothesis.   

Part (c)

F(2, 10) = 3.97

Fcrit =  

Retain the null hypothesis.Reject the null hypothesis.   

Part (d)

F(4, 37) = 2.72

Fcrit =  

Retain the null hypothesis.Reject the null hypothesis.    

Explanation / Answer

a) Fcrit = 2.93

as test statistic is higher than critical value

Reject the null hypothesis.   

b)

Fcrit = 2.77

as test statistic is less than critical value

Retain the null hypothesis.   

c)

Fcrit = 4.10

as test statistic is less than critical value

Retain the null hypothesis.   

d)

Fcrit = 2.63

as test statistic is higher than critical value

Reject the null hypothesis.
