Question
A group of third grade students is taught using a
new curiculum. 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 8766541160022246 66677
new method
reading test scores than the old method does?
Assume the population variances are equal.
Complete parts (a) through (e) below. Assume the
samples are random and independent, and the
populations are normally distributed.
