A study was conduced to investigate whether the mean number of snack bars sold at two airport convenience stores,C and D, were different. For ten randomly selected days, the number of snack bars sold at each store was recorded, and the sample mean number of snack bars for each store was calculated. A two-sample t-test for a difference in means will be conducted. Have all the conditions for inference been met? A.) Yes, all conditions have been met B.) No, the data were not collected using a random method C.) No, the sample sizs are greatr than 10 percent of the population D.) No, the sample sizes are not large enough to assume normality of the sampling distrbution E.) No, the distribution of the population is known to be skewed
