Is a person with a score of 79 more or less depressed than most other people who complete the scale? 2. Use Table 4.3 (pages 76-77 in your text) to find the following a.The area of the normal curve above a zscore of 1.71 b. The area of the normal curve between the mean and a zscore of -1.34 C.The zscore that marks the lower limit of the 38 percent of the curve immediately below the mean. Chapter 1. As an administrator of a local United Way agency. your job is to allocate funds for agencies that request them.

Explanation / Answer

1)

You can use the below formula to compute it:-

z=(x-)/

z=(79-89)/5

z=-10/5

z=-2

Looking at the z-table, we get the probability as 0.0228. That means about 97.72% of the persons are above him
