Question

The average starting salary for graduates at a university is $33,000 with a standard deviation of $2,000. If a histogram of the data shows that it takes on a mound shape, the empirical rule says that approximately 95% of the graduates would have a starting salary between _______.

Answer 1

Approximately $37000

Step-by-step 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
