Emi computes the mean and variance for the population data set 87, 46, 90, 78, and 89. she finds the mean is 78. her steps for finding the variance are shown below. mc008-1.jpg what is the first error she made in computing the variance? emi failed to find the difference of 89 - 78 correctly. emi divided by n - 1 instead of n. emi evaluated (46 - 78)2 as -(32)2. emi forgot to take the square root of -135.6.

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)
