An independent-measures research study uses two samples, each with n = 10 participants. If the data produce an observed t statistic of t = 2.095, which of the following is the correct decision for a two-tailed hypothesis test (α = .05?) a. Reject the null hypothesis b. Reject the null hypothesis c. Fail to reject the null hypothesis d. Cannot answer without additional information

a.Reject the null hypothesis

Explanation:

Null Hypothesis is rejected & not rejected as per following rules :

At significance level 0.05 two tailed test, implies 0.025 at each tail of the distribution. This corresponds to t statistic tabulated value = 1.96

The calculated value of t statistic = 2.095 [Given]

As t statistic's calculated value 2.095 > t statistic's tabulated value 1.96 The Null Hypothesis is rejected

this question your asking is true hope this and you get a 100 percent : )

im sorry i wish i can but try google
