Changing units in the customary system

Let w=23 . what is the value of w + 45 ?

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.)

How do you create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1?
