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 ? = .05, what is the correct statistical decision for this sample?

1. The researcher can reject the null hypothesis with ? = .05 but not with ? = .01.

2. The researcher can reject the null hypothesis with either ? = .05 or ? = .01.

3. The researcher must fail to reject the null hypothesis with either ? = .05 or ? = .01.
