Skittles are distributed throughout Europe in bags whose weights are normally distributed with mean weight 62 grams and standard deviatio n 4 grams. One particular factory in Zagreb, Croatia produces 15400 bags of Skittles per year. Using this information, select the response which correctly completes the following sentence: European Skittles are boxed in groups of 16 bags. This means the sampling distribution of Mean weights of bags within boxes has a standard deviation of gram(s). 0 1 O 4 O 2.45 O 16

A particular fruits weights are normally distributed, with a mean of 797 grams and a standard deviation of 17 grams. The heaviest 16% of fruits weigh more than how many grams?

Calculate the SEM (standard error of the mean) for the following data:a. Population standard deviation = 15b. Sample size = 25

The cost of unleaded gasoline in the Bay Area once followed an unknown distribution with a mean of $ 4.87 and a standard deviation of $ 0.05. A sample of 15 Bay Area gas stations are randomly chosen. We are interested in the average cost of gasoline for the 15 service stations. The distribution to use for the average cost of gasoline for the 15 service stations is: Select one: a. N (4.87, 0.0129) b. N (0.3247, 0.0006) c. N (4.87, 0.0033) d. N (4.87, 0.0002) e. N (0.3247, 0.0033)
