A researcher obtains t 225 for a repeatedmeasures study usi

A researcher obtains t = 2.25 for a repeated-measures study using a sample of n = 10 participants. Based on this t value, what is the correct decision for a two-tailed test? A. Reject the null hypothesis with = .05 but fail to reject with = .01. B. Reject the null hypothesis with either = .05 or = .01. C. Fail to reject the null hypothesis with either = .05 or = .01. D. Fail to reject the null hypothesis with = .05 but reject with = .01.

Solution

AT 0.01 LOS
Critical Value
The Value of |t | with n-1 = 86 d.f is 2.37
We got |to| =2.25 & | t | =2.37
Make Decision
Hence Value of |to | < | t | and Here we Do not Reject Ho

AT 0.05 LOS
Critical Value
The Value of |t | with n-1 = 86 d.f is 1.663
We got |to| =2.25 & | t | =1.663
Make Decision
Hence Value of | to | > | t | and Here we Reject Ho

A. Reject the null hypothesis with = .05 but fail to reject with = .01
