Reading Rate: Michael Sullivan, son of the author, decided to enroll in a reading course that allegedly increases reading speed and comprehension. Prior to enrolling in the class, Michael read 198 word per minute. The following data represents the words per minute read for 10 different passages after the course.

206 217 197 199 210
210 197 212 227 209

a) Because the sample size is small, we must verify that reading speed is normally distributed and the sample does not contain any outliers. The normal probability plot and boxplot are shown. Are the conditions for testing the hypothesis satisfied?

b) Was the class effective? Use the alpha=.10 level of significance. Use the classical method to solve.
