a. Calculate the mean for this population.
μ=
(Type an integer or a decimal.)

Answer 1

To calculate the mean for this population, we need to sum all the values and divide by the total number of values:

Mean = (9 + 24 + 23 + 3 + 45 + 15 + 30 + 23 + 52 + 49 + 13 + 41 + 11 + 45 + 50 + 51 + 25 + 39 + 65 + 23 + 70) / 20

Mean = 622 / 20

Mean = 31.1

Therefore, the mean for this population is 31.1.
