Asample 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 alpha = .05 but not with alpha = .01. (b) the researcher can reject the null hypothesis with either alpha = .05 or alpha = .01.(c) the researcher must fail to reject the null hypothesis with either alpha = .05 or alpha = .01.(d) it is impossible to make a decision about h0 without more information.
