An independent-samples research study uses two samples, each with n = 12 participants. If the data produce a t-statistic of t = 2.50, then which of the following is the correct decision for a two-tailed hypothesis test?           Reject the null hypothesis with α = .05 but fail to reject with α = .01. Reject the null hypothesis with either α = .05 or α = .01. Fail to reject the null hypothesis with either α = .05 or α = .01. Fail to reject the null hypothesis with α = .01, but reject the null with α = .05. The results of an independent-samples study are reported as “t (20) = 2.12, p < .05, two-tailed.”        For this study, what tcritical values form the boundaries for the critical region?     ± 2.093 ± 2.086 ± 2.080 ± 2.074

Can someone help me understand these two questions I'm not sure how to find the answers? 

An independent-samples research study uses two samples, each with n = 12 participants. If the data produce a t-statistic of t = 2.50, then which of the following is the correct decision for a two-tailed hypothesis test?          

  1. Reject the null hypothesis with α = .05 but fail to reject with α = .01.
  2. Reject the null hypothesis with either α = .05 or α = .01.
  3. Fail to reject the null hypothesis with either α = .05 or α = .01.
  4. Fail to reject the null hypothesis with α = .01, but reject the null with α = .05.

The results of an independent-samples study are reported as “t (20) = 2.12, p < .05, two-tailed.”        For this study, what tcritical values form the boundaries for the critical region?    

  1. ± 2.093
  2. ± 2.086
  3. ± 2.080
  4. ± 2.074
