Question

You are given n = 5 measurements: 5, 3, 3, 8, 8. (a) calculate the sample mean, x. (enter your answer to one decimal place.)

Answer 1

The mean  = sum of all the measurements / number of measurements (n)

                 =  (5 + 3 + 3 + 8 + 8)  / 5

                 =   27 / 5

                 = 5.4  Answer
