What is the decision at a 0.05 level of significance for each of the following tests?...

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, 25) = 3.07

F_crit =

Retain the null hypothesis or Reject the null hypothesis.
Part (b)

F(5, 21) = 2.53

F_crit =

Retain the null hypothesis or Reject the null hypothesis.
Part (c)

F(4, 33) = 2.75

F_crit =

Retain the null hypothesis or Reject the null hypothesis.
Part (d)

F(2, 14) = 3.69

F_crit =

Retain the null hypothesis or Reject the null hypothesis.

Answer 1

Answer #1

From F table output, the required critical values and decision will be:

a) Fcrit = 2.99

Reject the null hypothesis

b) Fcrit = 2.68

Retain the null hypothesis

c) Fcrit = 2.66

Reject the null hypothesis

d) Fcrit = 3.74

Retain the null hypothesis

Suppose a hypothesis test is conducted using a significance or alpha level of 0.05, and the null hypothesis is rejected. This means that? A we would also reject the null hypothesis if the significance level had been 0.10 instead of 0.05. B the p-value was greater than 0.05. C we would also reject the null hypothesis if the significance level had been 0.01 instead of 0.05. D All answer options are correct.
