Question

Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis or (b) fails to reject the null hypothesis? A scientist claims that the mean incubation period for the eggs of a species of bird is more than 41 days. Does the claim represent the null hypothesis or the alternative hypothesis? Since the claim (a) How should you interpret a decision that rejects the null hypothesis? There is (b) How should you interpret a decision that fails to reject the null hypothesis? There is a statement of equality, it represents the hypothesis V evidence to Vthe claim that the mean incubation period for the eggs of a species of bird is more than 41 days. V evidence to the claim that the mean incubation period for the eggs of a species of bird is more than 41 days.

Explanation / Answer

Given that a scientist claim that the mean incubation period for the eggs of a species of birds is more than 41 days.

This claim represents the alternative hypothesis.

Since the claim is not a statement of equality, it represents the alternative hypothesis.

a) There is a sufficient/enough evidence to justify the claim that the mean incubation period for the eggs of a species of birds is more than 41 days.

b) The interpretation of the decision that fails to reject the null hypothesis is:

There is no sufficient evidence to justify the claim that the mean incubation period for the eggs of a species of birds is more than 41 days.
