Chapter 5, Section 1, Exercise 012 Incorrect. The following is a set of hypotheses, some information from one or more samples, and a standard error from a randomization distribution. Test Ho : ?? = ?2 vs Ha : ? > ?2 when the samples have n = n, = 40, ??35.7, x, = 33.1, s? = 1.24, and $2 1.11. The standard error of Ti from the randomization distribution is 0.26.

Chapter 5, Section 1, Exercise 027 Smile Leniency An experiment has been conducted to study the effects of smiling on leniency in judging students accused of cheating. The figure below shows a dotplot of a randomization distribution of differences in sample means. The relevant hypotheses are Ho : ?., ?? vs Ha : ?.> ??, wherep, and ?" are the mean leniency scores for smiling and neutral expressions, respectively. This distribution is reasonably bell-shaped and we estimate the standard error...
