To assess the effectiveness of a cola video ad for cola B, a random sample of 35 individuals from a target audience was selected to participate in a copy test. Participants viewed two ads, one ofwhich was the ad being tested (cola B). Participants then answered a series of questions about how much they liked the ads. An adindex measure was created and shown in the accompanyingtable; the higher the adindex value, the more likeable the ad. State your findings and conclusions.

Warren wants to know if the amount of coffee that you drink is related to the number of hours that you stay awake. He recruits 50 participants using random sampling to report how much coffee they drank and the time of the day that they went to sleep. He then performs a correlation to determine the association between the amount of coffee that was consumed and the number of hours that they stayed awake. There was a statistically significant positive correlation between amount of coffee that participants drank and the number of hours that they stayed awake, r(49) = .82, p < .05, two-tailed, r2 = .08. This was a small effect – 8% of the variance in the amount of coffee drank is explained by hours that you stay awake (and vice versa).

Houston North Hospital is trying to improve its image by providing a positive experience for its patients and their relatives. Part of the "image" program involves providing tasty, inviting patient meals that are also healthful. A questionnaire accompanies each meal served, asking the patient, among other things, whether he or she is satisfied or unsatisfied with the meal. A 100-patient sample of the survey results over the past 7 days yielded the following data: Day 1 234 5 6 7 The control limits to include 99.73% of the random variation in meal satisfaction are: No. of Unsatisfied Patients ZNORDRH 22 22 6 15 10 28 17 UCLp = = .284 (enter your response as a number between 0 and 1, rounded to three decimal places).
