1, In a paired samples design, famous cowboys were paired with their famous Indian antagonists and an honesty index was derived for each. The cowboy mean was 46 and the Indian mean was 75. A t test produced a value of 2.15. Given an α level of .05, which conclusion below is correct? (High scores mean more honesty.)

2, In an independent samples design, the Dog's mean was 54.0 and the Cat's mean was 53.9. Larger scores are better. A t value of 2.50 was calculated and an α level of .05 adopted. Which conclusion is appropriate with a 2-tailed test?

3, Two schedules for giving rest were compared—the massed schedule and the spaced schedule. Twenty observations of the spaced schedule produced a mean of 26 errors. On the massed schedule 14 observations resulted in a mean of 36 errors. An α level of .05 was adopted and an F = 4.21 was obtained. What conclusion is appropriate?
