The students from the Liberal Arts College drank a mean of 8 drinks per week and students from the business school drank a mean of 10 drinks per week. Use this data to answer questions a-e: a. If So = 1.6, calculate g (the sample estimate of d). (1 pt) b. What size effect is this? (1 pt) c. Calculate 6. (2 pts) d. If a =.05, two-tailed, what is the power of this study? (1 pt) e. What is the probability of a Type II error (beta) for this study? (1 pt)
