Begin by entering the data starting with J2 to get the sample variance and sample size n. Use those values to complete the C6 to C8. For C4, change the direction of the arrow to reflect the claim. Finish by entering the claim value in D4 Results: Is there enough evidence to support his claim? Give your answer in complete sentences. Justify your answer either by using a rejection region or a p-value argument.
