Exercise #2 [15pt] A group of third-grade students is taught using a new curriculum. A control group of third-grade students is taught using the old curriculum. The reading test scores for the two groups are shown in the back-to-back stem-and-leaf plot. At a 0.01, is there enough evidence to support the claim that the new method of teaching reading produces higher reading test scores than the old method does? Assume the population variances are equal. Assume the samples are random and independent, and the populations are normally distributed.
