Question

A researcher is testing a null hypothesis stating that for the general population there is no preference between the two leading brands of cola. In a sample of n = 100 people, 40 preferred brand A and 60 preferred brand B. Assuming that the researcher uses a two-tailed test, what is the appropriate statistical decision?

Reject the null hypothesis with either α = .05 or α = .01.

Reject the null hypothesis with α = .05 but not with α = .01.

No decision is possible without additional information.

Fail to reject the null hypothesis with either α = .05 or α = .01.

Fail to reject the null hypothesis with α = .05 but not with α = .01.
