An analysis of variance test has been performed and results in rejecting the Null hypothesis. Below are the results of Tukey'scomparison. Determine which mean is different.

Comparison lower bound upper bound

mean 1 compared -0.84 1.55

to mean 2

mean 1 compared 1.62 3.05

to mean 3

mean 2 compared 0.55 1.98

to mean 3

a. mean 1 is different than means 2 and 3

b. mean 2 is different than means 1 and 3

c. mean 3 is different than means 1and 2

d. All three means are different
