Question

Eight oranges were selected at random from a crate of 53 oranges. Their diameters were measured, in millimeters, and then recorded. Diameters: 45, 46, 42, 53, 60, 49, 54, 51 What is the estimated mean diameter of the 53 oranges in the crate?

Answer 1

Order:
42, 45, 46, 49, 51, 53, 54, 60

Add:
42 + 45 + 46 + 49 + 51 + 53 + 54 + 60 = 400

Divide:
400 / 8 (the number of numbers being used)

Answer: 
50 = Mean

Answer 2

50 is the mean because you add all the diameters then divide by 8
