A hypthesis test with a sample of n30 participants produces

A hypthesis test with a sample of n=30 participants produces a t statistic of t=2.33. Assumig a one-tailed test, wht is the correct decicion about the outome of the test?

a. the researcher can reject the null hypothesis with a =.05 butnot with a=.01

b. the researcher can reject the null hypothesis with a= .01 but not with a=.05

c. the researcher can reject the null hypothesis with either a= .05 or a= .01

d. the rresearher must fail to reject the null hypothesis with ether a= .05 or a= .01

e. cannot be detemined

Solution

Using table/technology, we can get the p value, as df = n - 1 = 29, t = 2.33,

P = 0.013486083

Thus, we reject Ho if this is lower than the significance level, like 0.05, but not 0.01.

Thus,

OPTION A: the researcher can reject the null hypothesis with a =.05 but not with a=.01 [ANSWER]
