D Question 7 5 pts Do good smells bring good business? Businesses know that customers often respond to background music. Do they also respond to odors? An experiment asked whether background aromas in a restaurant encourage customers to stay longer and spend more. It was conducted on two separate Saturday evenings in a small pizza restaurant in France that were reasonably comparable in all other ways (weather, customer count, and so on) beside the lavender odor on the second evening. For each Saturday night, ten customers were randomly selected by simple random sampling, so a total of twenty customers were observed for the whole study. It was made sure that no customer was selected more than once. The amount each customer spent on the restaurant that night were recorded. A. Are the samples related or independent? [ Select ] B. Based on the results of the formal test for checking normality, is the normality assumption met at the 5% level of significance? [ Select ] No Odor (X1) Lavender Odor (X2) Differences (X1-X2) p-value (formal test for 0.9348 0.8913 0.917 checking normality) C. Assume that the samples are independent and you want to check the checking for the homogeneity of the variance. The test gives you an f-statistic of 1,18197 and a p-value of 0.38582. Is the homogeneity of variance assumption met at 5% level of significance? [ Select ]
