A random sample of employees from a local manufacturing plant pledged the following donations, in dollars, to the United Fund: 100, 40, 75, 15, 20, 100, 75, 50, 30, 10, 55, 75, 25, 50, 90, 80, 15, 25, 45, and 100.

Calculate
(a) the mean;

Answer 1

The mean donation from the sample of employees is calculated to be $50.25.

Step-by-step explanation:

To calculate the mean donation from the provided data, we add up all the donation values and then divide by the number of donations.

• Sum of donations = 100 + 40 + 75 + 15 + 20 + 100 + 75 + 50 + 30 + 10 + 55 + 75 + 25 + 50 + 90 + 80 + 15 + 25 + 45 + 100 = 1005
• Number of donations = 20
• Mean donation = Sum of donations / Number of donations = 1005 / 20 = 50.25

The mean donation to the United Fund by the employees is $50.25.
