A sample has a mean of M = 39.5 and a standard deviation of s = 4.3,and produces a t statistic of t = 2.14.For a two-tailed hypothesis test with α = .05,what is the correct statistical decision for this sample? A)The researcher can reject the null hypothesis with α = .05 but not with α = .01. B)The researcher can reject the null hypothesis with either α = .05 or α = .01. C)The researcher must fail to reject the null hypothesis with either α = .05 or α = .01. D)It is impossible to make a decision about H₀ without more information.
