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.
