Thez-score will be2.78

Step by step solution

01

Given Information

The z-score of x= 鈥�2, if it is2.78 standard deviations to the right of the mean?

02

Explanation

By using the z-scoreit can be calculated by how many standard deviations (蟽), the value of x will lie down (left) or overhead (right) the mean (渭) of the distribution. Since it is delivered that the z-score is 2.78standard deviations to the right of the mean for x=-2.
