If the absenteeism rates for a school district rise above 10%, the state reduces its aid to the school district. Stermerville independent school district takes a sample of five schools within the district and finds the following absenteeism rates:5.4%,8.6%,4.1%,8.9%, and 7.8%. What is your best estimate of the absenteeism rate in Stermerville? Is it likely that the absenteeism rate is greater than 10%?

Use a hypothises test to determine if the proportions are statistically different.

A recent survey showed that in a sample of 100 elementary school teachers, 15 were single. In a sample of 180

high school teachers, 36 were single. Is the proportion of high school teachers who were single greater than the

proportion of elementary teachers who were single? Use ΅ = 0.01.

Students in a school were asked to participate in a study of the effects of a new teaching method on reading skills of 10th graders. To determine the effectiveness of the new method, a reading test was given to each student before applying the new method (pre-test). Another test was given to the same students after applying the new method (post-test). Experts consider that a good measure of improvement is given by the following formula: Improvement=20(Post-test score)- 10(Pre-test score). That is, improvement is 20 times the post-test score minus 10 times the pre-test score. An improvement ? 300 is considered good. It is known that the average score in the pre-test is 40, average score in the post-test is 40, standard deviation in the post-test is 6, standard deviation in the pre-test is 5, and correlation between the scores in the two tests is 0.5

What is the standard deviation of the improvement?

Write the Variance covariance matrix for the pre and post-test scores vector random variable.

Ban Vallew has a son, Katt, by a previous marriage. Ban’s ex-wife has custody of Katt. Katt Vallew has a history of emotional problems, for which he has seen a psychiatrist for several years. This year he has become so disturbed, manifesting violence at home and school, that he was enrolled in a special school in Arizona for problem children.

a. List as many possible tax research issues as you can to determine tax treatment(s) available to Ban on the payments to the school.

b. After completing your list of tax research issues, list the keywords you might use to construct an online tax research query.

During the recent graduation season in Namibia a total of 8000 students graduated from three different universities UNAM, NUST and IUM. Of the 8000 graduates, 4000 students graduated from UNAM, 3000 students graduated from NUST, while the rest of the students graduated from IUM. A total of 85 out of every 100 students from UNAM graduated from their Business School, while at NUST, 65 out of every 100 students graduated from their Business School, and at IUM, 60 out of every 100 students graduated from their Business School. The Minister of Education in Namibia, randomly selects a student who graduated during this graduation season:

1.1) Find the probability that the selected graduate is from a Business School. (7)

1.2) Calculate the probability that the randomly selected graduate from a Business School is from NUST. (5)
