: Independent Samples t Test Criterion: Identify IV, DV, and hypotheses and evaluate the null hypothesis for an independent samples t test. Data:

  • Minutes of practice:
    • Group 1: 55, 44, 62, 30, 78, 50, 52.
    • Group 2: 31, 40, 53, 22, 41, 16, 33.

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.
