Question
Randomly selected students were given five seconds to estimate the value of a product of numbers with the results shown below.
Estimates from students given 1 x 2 × 3 x 4 x 5 x 6 x 7 x 8:
500, 150, 500, 42200, 560, 25, 5000, 842, 2000, 600
Estimates from students given 8 x 7 x 6 x 5 x 4 × 3 × 2 × 1:
450, 3600, 42000, 52836, 400, 40000, 2000, 5000, 428, 25000
Use a 0.05 significance level to test the claim that the two populations have the same mean.
(a) The standardized test statistic is
(b) The conclusion is
O A. There is sufficient evidence to warrant the rejection of the claim that the two populations have the same mean
O B. There is not sufficient evidence to warrant the rejection of the claim that the two populations have the same mean
