A researcher is conducting a two-tailed hypothesis test (alpha=.05) among 39 adults from Omaha to examine whether there are significant differences between women and men in their views on gun control safety in Omaha. When looking at the t-table to choose a critical score, he finds that the degrees of freedom falls in-between 2 numbers. Why does he choose the higher t(critical) score, 2.042, rather than 2.021? Check all that apply a. Because choosing the higher critical score is a more liberal test. b. Because choosing the higher critical score is a more conservative test. c. Because choosing the higher critical score reduces the likelihood of Type I error. d. Because choosing the higher critical score reduces the likelihood of Type II error. e. Because choosing the higher critical score makes it easier to reject the null. f. Because choosing the higher critical score makes it more difficult to reject the null.
