Example 6.2 from Statistics, 6.1 The Standard Normal Distribution

(part 2)

b. Suppose a person gained three pounds, a negative weight loss. Then z = __________. This z-score tells you that x = –3 is ________ standard deviations to the __________ (right or left) of 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.

Solution
b. z = –4. This z-score tells you that x = –3 is four standard deviations to the left of the mean.

How did it go?
