Random samples of 13 women and 11 men yielded the following scores on a test:
Women: 70, 78, 62, 96, 75, 68, 41, 74, 80, 47, 73, 94, 65 Men: 72, 60, 52, 87, 66, 74, 95, 50, 81, 70, 72
Use a 0.05 significance level to test the claim that test scores for women have a larger standard deviation than test scores for men.
(Note:s1=15.588 ands2=13.754).

To achieve this goal, the company recommends that students take a core curriculum of math courses in high school. Suppose a random sample of 150 students who completed this core set of courses results in a mean math score of 21.4 on the college entrance exam with a standard deviation of 3.2. Do these results suggest that students who complete the core curriculum are ready for college-level mathematics? That is, are they scoring above 21 on the math portion of the exam?

The table shows results from a study of the MPG (miles per gallon) of cars both in the city and on the highway. Assume that the two samples are randomly selected, independent, the population standard deviations are not know and not considered equal. At the 0.1 significance level, test the claim that the mpg on the highway is better than in the city.

- Determine if the outcome is unusual. Consider as unusual any result that differs from the mean by more than 2 standard deviations. That is, unusual values are either less than u - 20 or greater than u + 20. According to AccuData Media Research, 36% of televisions within the Chicago city limits are tuned to "Eyewitness News" at 5:00 pm on Sunday nights. At 5:00 pm on a given Sunday, 2500 such televisions are randomly selected and checked to determine what is being watched. Would it be unusual to find that 981 of the 2500 televisions are tuned to "Eyewitness News"?

An experiment is conducted and data are collected from 29 males and 16 females. The males took an average of three English courses with a standard deviation of 0.8. The females took an average of four English courses with a standard deviation of 1.0. Are the means statistically the same?
