37. In order to decrease the chances of making a Type I error, you can: a. Decrease the sample size Decrease alpha Increase the variability in the standard error of the null populations Hold power constant while increasing the probability of a Type 11 error P-PP' 38. With regards to e'ect size estimators, eta-squared (n2) is A statistic; a parameter Unbiased; also unbiased Less biased; more biased More biased; less biased and omega-squared (032) is 999'?\" 39. Ifyou have a set of scores and add 2 to every score, how will the standard deviation change? a. The new standard deviation and the old standard deviation will be the same b. The new standard deviation will be twice as large as the old standard deviation c. The new standard deviation will be half the size (twice as small) as the old standard deviation d. Not enough information to answer this question 40. Abag of M&Ms contains 3 brown, 4 red, 10 blue, and 6 yellow M&Ms. The probability of choosing a red M&M followed by a yellow M&M, with replacement is 0.04537. a. True b. False 41. You have a group of 24 individuals whom you have divided into four equal groups of 6. Using these groups, you want to see if type of classroom instruction (traditional lecture, distance learning, self-guided discovery, classroom debate) has an impact on test scores. Using this information and an alpha of .01, what would the critical value for a Fisher's LSD test he
