A state school administrator claims that the standard deviations of science assessment test scores for eighth-grade students are the same in Districts 1 and 2. A sample of
10 test scores from District 1 has a standard deviation of 34.2 points, and a sample of 12 test scores from District 2 has a standard deviation of 31.2 points. At g=0.01. can
you reject the administrator's claim? Assume the samples are random and independent, and the populations are normally distributed. Complete parts (a) through (e)
