Your response should be at least 75 words in length. You are required to use at least your textbook as source material for your response. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying citations.

2. Using Case Exhibit 21.1-1 on page 527 in the textbook, formulate a statistical hypothesis appropriate for the consumer group's purpose, then calculate the mean average miles per gallon. Compute the sample variance and sample standard deviation. Determine the most appropriate statistical test using the 0.05 significance level.

2	24.5	14	26.7
3	31.2	15	31
4	28.7	16	23.5

9	31	21	28.4
10	30.2	22	29.1
11	28.4	23	21.9
12	29.3	24	30.9

Your response should be at least 75 words in length. You are required to use at least your textbook as source material for your response. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying citations.

3. Using the SPSS Output from Case Exhibit 22.1-1 on page 551 of your textbook, comment on the appropriateness of the statistical test used (make sure that your response includes information on the types of variables used and the scales of measurement). Describe an alternative approach that may be used.

Your response should be at least 200 words in length. You are required to use at least your textbook as source material for your response. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying citations.
