Find the test statistic F to test the hypothesis that the populations have the same mean. Use ? = 0.05

a. 0.832

b. 1.403

c. 1.021

d. 1.182

Brand 1 n1 = 8 x1 = 3.0 $1 = 0.50 Brand 2 n2 = 8 X2= 2.6 s2 = 0.60 Brand 3 n3 = 8 x3 = 2.6 s3 = 0.55

Answer : b. 1.403

critical value F0 = 3.47;

test statistic F 1.403;

fail to reject H0;

The data does not provide enough evidence to indicate that the means are unequal.
