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 researcher claims that the standard deviation of the life of a certain type of lawn mower is less than 2.4 years

Does the claim represent the null hypothesis or the alternative​ hypothesis?

Since the claim a) -------- a statement of​ equality, it represents the b)------- hypothesis.

Options for a: contains or does not contain

Option for b: null or alternative hypothesis

less than 2.4 years.

Option for a: sufficient or insufficient

Option for b: Support or not reject

​2. How should you interpret a decision that fails to reject the null​ hypothesis?

There is a)------ evidence to not b)--------- the claim that the standard deviation of the life of a certain type of lawn mower is
