Question

find the z - score that has 88.1331% of the distributions area to its right. the z - score is . (round to two decimal places as needed.)

Explanation:

Step1: Find left - hand area

The total area under the standard normal curve is 1. If the area to the right of the z - score is 0.881331, then the area to the left of the z - score is $1 - 0.881331=0.118669$.

Step2: Use z - table

We use the standard normal distribution table (z - table) to find the z - score corresponding to an area of 0.118669. Looking up this value in the body of the z - table, we find that the z - score is approximately - 1.18.

Answer:

  • 1.18
