Question

use the ti - 84 plus calculator to find the z - score for which the area to its left is 0.59. round the answer to two decimal places. the z - score for the given area is 0.23.

Explanation:

Step1: Use the invNorm function on TI - 84 Plus

The invNorm function on the TI - 84 Plus calculator is used to find the z - score corresponding to a given left - tail area. The syntax is invNorm(area, μ, σ), where for the standard normal distribution μ = 0 and σ = 1. Here, the area to the left is 0.59, μ = 0, and σ = 1.
invNorm(0.59,0,1)

Step2: Read the result

When we execute the invNorm(0.59,0,1) command on the TI - 84 Plus calculator, we get the z - score.

Answer:

0.23
