Statistics

Randomly selected statistics students were given five seconds to estimate the value of a product of numbers with a summary of the results of both groups given below. Does the order of the numbers appear to have an effect on the variances? Use a 0.05 significance level to test the difference between variances of the two samples. Use the traditional method to perform the test.

Order 1: Estimates from 40 Students Given: 1 X 2 X 3 X 4 X 5 X 6 X 7 X 8

n = 28 x-bar = 28,344.9 s = 5,667.9

Order 2: Estimates from 42 Students Given: 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1

n = 25 x-bar = 36,001.0 s = 7,679.4
