Question

Use Table A in the back of the book to find the proportion of observations from a standard Normal distribution that fall in each of the following regions. In each case, sketch a standard Normal curve and shade the area representing the region.

$\text{2.}z>-2.15$

Short answer

The standard Normal curve, with the region represented by the area, is as follows:

Step-by-step solution

Given Information  

Z-score :$z>-2.15$

Explanation  

From Table A:

$$\begin{gathered} P(z>-2.15)=P(z<2.15) \\ =0.984222 \end{gathered}$$
