This questiоn hаs twо pаrts (а and b). Be sure tо answer both in the response/answer box below. A travel agency wants to test for a difference in customer satisfaction at two hotel chains, Sleep Well and Comfort Stay. To test this, the group surveyed two groups. A sample of 49 customers who stayed at Sleep Well reported a mean satisfaction level of 76, with a sample standard deviation of 11. A different sample of 36 customers who stayed at Comfort Stay had a mean satisfaction score of 71, with a sample standard deviation of 10. Part a: Briefly explain why a "paired differences/matched sample" test might have been a better way (as opposed to the two-sample approach used in the previous problem) to answer the question of whether there is a difference in customer satisfaction at these two hotel chains. Part b: Briefly describe how you could have tested this question as a “paired differences/matched sample" test rather than the way it was tested in the previous problem. Make sure you describe how your experiment would be different in the context of the question (Sleep Well vs Comfort Stay). [Note: You are not being asked to do a paired-differences test. Just describe how you would have set up this experiment if you wanted to use a paired-differences approach.]
