Question

Calculate the range, population variance, and population standard deviation for the following data set. If necessary, round to one more decimal place than the largest number of decimal places given in the data.

10,9,4,9,5,5,7,4,8,34

Answer 1

range = maximum - minimum

mean = sum of values/number of values

variance = [sum (value(i) - mean)^2]/number of values, where i = 1 through 10

standard deviation = square root (variance)
