C please

An annual championship event is the most widely watched sporting event in a country each year. In recent years, there has been a great deal of interest in the ads that appear during the game. These ads vary in length with most lasting 30 seconds or 60 seconds. The accompanying data represent the ad length and ad scores from a recent championship. Complete parts (a) through (c).

30-Second Ads	60-Second Ads
48	27	40	39	47	65	59	58	60	53
40	23	36	53	54	24	39	38	47	61

a. Assuming that the population variances from the 30-second ads and the 60-second ads are equal, is there evidence of a difference in the mean score between the two types of ads? Use

α=0.02.

Let

μ1

be the mean score for the 30-second ads and

μ2

be the mean score for the 60-second ads. Determine the hypotheses. Choose the correct answer below.

H0:

μ1≥μ2

H1:

μ1<μ2

H0:

μ1=μ2
