Answer:

Approximately $37000

Explanation:

A standard normal curve will be used to solve this question since the histogram of the data takes on a mound shape.

The mean salary is $33000 with one standard deviation equalling $2000.

Using the normal curve, 95% of the salary will lie between 2 standard deviation. i.e. $33000+$2000+$2000=$37000
