Criterion: Identify IV, DV, and hypotheses and evaluate the null hypothesis for an independent samples t test. Data: Use the information from Problem Set 3.8. Instructions: Complete the following: a. Identify the IV and DV in the study. b. State the null hypothesis and the directional (one-tailed) alternative hypothesis. c. Can you reject the null hypothesis at α = .05? Explain why or why not.

The table is missing in the question. The table is provided here :

Group 1        Group 2

 34.86            64.14      mean

 21.99            20.46      standard deviation

  7                    7                n

Solution :

a). The IV or independent variable = Group 1

    The DV or the dependent variable = Group 2

b).

  Therefore,  

t = -2.579143

Now,  

           df = 7 - 1

               = 6

Therefore the value of p :

 = 0.020908803

The p value is 0.0209

So we reject the null hypothesis and conclude that
