3) A school administrator claims that the standard deviations of math assessment scores for 8th grade students are the same in Districts 3 and 4. A random sample of 12 scores in District 3 had a standard deviation of 36.8 points and a random sample of 14 scores in District 4 had a standard deviation of 32.5 points. At ? = 0.10, what can be said about the administrator’s claim? Assume the populations are normally distributed and complete all seven steps.

A random sample of 86 eighth grade students’ scores on a national mathematics assessment test has a mean score of 294. This test result prompts a state school administrator to declare that the mean score for the state’s eighth graders on this exam is more than 285. Assume the population standard deviation is 35. At the 3 % level of significance, is there enough evidence to support the administrator’s claim?

A school administrator believes that taking an online prep course prior to enrollment in a math course will improve your overall course grade. Suppose that the average course grade is 621 points (out of 800 possible) with a standard deviation of 32 points. A sample of 30 students who took the prep course had a mean course grade of 618 points. At the 6% significance level, is there enough evidence to suggest that taking the prep course really does improve...
