Melo increase sample Size 8. Engineers want to design seats in commercial aircraft so that they are wide enough to fit 98% of all males. Men have hip breadths that are normally distributed with a mean of 14,4 in and a standard deviation of 1.0 in. Find PM the hip breadth for men that separates the smallest 98% of men from the largest 2%. [You can use invNorm on (6.3) [8 points) X-14.4 this one.] N = 14.4 -1.0 P(x > Z) = 0.98 XYZ 9. Assume that a procedure yields a binomial distribution with n trials and the probability of success on (5.3) one trial is p. Use the given values of n and p to find the mean u and standard deviation o. [6 points] In a Gallup poll of 1025 randomly selected adults, 68 % said they worry about identity theft. So n = 1025 and p = 0.68.
