Example 6.2 from Statistics, 6.1 The Standard Normal Distribution
a. Suppose a person lost 10 pounds in a month. The z-score when x = 10 pounds is z = 2.5 (verify). This z-score tells you that x = 10 is ________ standard deviations to the ________ (right or left) of the mean _____ (What is the mean?).
Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.
a. This z-score tells you that x = 10 is 2.5 standard deviations to the right of the mean five.
How did it go?
