A population of values has a normal distribution with mean of 165.7 and standard deviation of 60.2. a) Get the z-score for a value of 163. For this problem you use the z score formula z=x−μσz=x-μσ    b) This z-score tells you how many  the score of 163 is above or below the population mean μμ . c) Find the probability that a randomly selected value is greater than 163.   Part 2 A population of values has a normal distribution with mean...
