A sheriff's department claims that it pays its male and female employees equal wages. You analyze the wages they actually paid the deputies, and you find that the average hourly wage for males was $13.50 and for females it was $12.30. You conduct a t-test for this difference and get a t(obtained) of 1.31. (Hint: you will be using the two-sample hypothesis test) a. State the appropriate null and research hypotheses. b. If you had an alpha of .05 (one-tailed) with 60 degrees of freedom, what would be your t(critical)? c. Pretend you have a t(critical) of +2.000. Pretend you also calculated a t(obtained) of +1.31, write out a full interpretation based on the problem description above.
