1 pts The student academic group on a college campus claims that first-year students study around 2.5 hours per day, on average. However, one Introduction to Statistics class at Emory believed that the average would be significantly greater than 2.5 hours per day, so they took a random sample of 40 first-year students to perform a two-sided hypothesis test. At a = 0.01 level, what is the smallest test statistic they need to acquire in order to reject the null hypothesis? O 2.83 02.53 0 2.75 0 2.78 Question 14 1 pts A psychologist wants to determine if socioeconomic status is related to game-playing preferences. Fifty children, in total, were identified from families of low, middle, and high socioeconomic status, and each child was asked to select one game of the following: Monopoly, Battleship, or Connect Four. The psychologist performed a chi-squared test which yielded a test statistic of 5.0. What can we say about the p-value, H,, and the conclusion at the a=0.05 level of significance? O 0.2 <p-value < 0.3; fail to reject Ho, there is evidence of an association between socioeconomic status and game preference. O p-value > 0.3; fail to reject Ho; no evidence of an association between socioeconomic status and game preference. O 0.05 p-value < 0.1; reject Ho; there is evidence of an association between socioeconomic status and game preference. O 0.2 <p-value < 0.3; fail to reject Ho; no evidence of an association between socioeconomic status and game preference.
