Using a mean of 100 and a standard deviation of 15: a.) Is an IQ score of 130 an outlier? Explain why or why not. (this does not use deviations) b.) is an IQ score of 140 an outlier? Explain why or why not 12.) The U.S. Air Force requires that pilots have heights between 64 in. and 77 in. a) Using the parameter that women's heights are normally distributed with a mean of 63.8 in. and a standard deviation of 2.6 in., find the percentage of women meeting the height requirement. b) Using the parameter that men's heights are normally distributed with mean 69.5 in and standard deviation 2.4 in, find the percentage of men meeting the height requirement. c) if the Air Force height requirements are changed to exclude only the tallest 3% of men and the shortest 3% of women, what are the new height requirements? 13. Based on one data set, M&M plain candies have a mean weight of 0.8565 g and a standard deviation of 0.0518 8. The M&M candies used in this dataset came from a package containing 465 candies, and the package label stated that the net weight is 396.92 (if every package has 465 candies, the mean weight of the candies must exceed 396.9/465 -0.8535 g for the net contents to weigh at least 396.9 l. a.) 11 M&M puin candy is randomly selected, find the probability that it weighs more than 0.8535 b.) If 465 M&M pisin candies are randomly selected, find the probability that their mean weight is at least 0.8535 c. Given these results, does it seem that the Mars Company is providing M&M consumers with the amount claimed on the label? Explain your answer and reasoning using complete sentences 14.)
