Chapter 2: Q.74 (page 135)

The proportion of observations from a standard Normal distribution with values larger than $- 0.75$ is
(a) $0.2266$ . (c) $0.7734$ . (e) none of these
(b) $0.7422$ . (d) $0.8023$ .

Short Answer

Correct answer is

Step by step solution

Given information

Standard Normal distribution with values larger than $- 0.75$ .

We have to find the proportion of observations.

Step 2: Explanation

Find the probability corresponding to $- 0.75$ using table A:

$P = 0.2266$

By comparing $0.2266$ of all observations, we can see that it is less than $- 0.75 .$

The total proportion being $1$ , this proportion is larger than $- 0.75$ , since $1 - 0.2266 = 0.7734$ of all observations.
