2.A college placement officer wants to determine whether male and female business graduates, on average, have different salary offers for their first position after graduation. The placement officer randomly selects eight pairs of business graduates in such a way that the qualifications, interests, and backgrounds of the members of any pair were as similar as possible. The major difference was that one member of each pair was male and one was female. The accompanying table shows the highest salary offer received by each sample member at the end of the recruiting round. Assuming that the distributions are normal. Find the 95 percent confidence interval and interpret the results. Pair 1 3 4 5 6 7 8 Male 26200 24700 28400 21700 28600 29300 28300 24300 Female 22600 23600 29300 22300 26200 25900 28500 21300

Does the location of your seat in a classroom play a role in attendance or grade? 1600 students in a physics course were randomly assigned to one of four groups. The 400 students in group 1 sat 0 to 4 meters from the front of the class, the 400 students in group 2 sat 4 to 6.5 meters from the front, the 400 students in group 3 sat 6.5 to 9 meters from the front, and the 400 students in group 4 sat 9 to 12 meters from the front. Complete parts (a) through (c). Click the icon to view the chi-square table of critical values. (a) For the first half of the semester, the attendance for the whole class averaged 83%. So, if there is no effect due to seat location, we would expect 83% of students in each group to attend. The data show the attendance history for each group.

A real-estate appraiser wants to verify the market value for homes on the east side of the city that are very similar to size and style. The appraiser wants to test the popular belief that the average sales price is $37.80 per square foot for such homes. Suppose that a random sample of six sales were selected. The sampled sales prices per square foot are $35.00, $38.10, $37.20, $29.80, $30.30, and $35.40. Assuming a normal distribution is a good model for sales, test the claim that the mean sales price per square foot differs from $37.80 at the 1% significance level.
