Answer 1

Step-by-step explanation:

Given that the mean annual salary at the company where Rasheia works is $48,000

The standard deviation is $6,000

Rasheia's salary is $53,000

Her salary is $5,000 greater than the mean salary.

This is within the standard deviation, and makes it NOT ABNORMAL.

Therefore,

Rasheia's salary falls within the standard deviation, so her salary is not abnormal compared to other salaries at this company.
