Disadvantage groups, notably Blacks and Hispanics. Have had smaller high school graduation rates and so less access to college than Whites. Among those with college degrees is an educational success beyond college similarly affected? To address this question use the data below. sample of 30-year-old Americans with college degrees.

e) give an appropriate conclusion in statistical and everyday language.

Old School Publishing Inc. began printing operations on January 1. Jobs 301 and 302 were completed during the month, and all costs applicable to them were recorded on the related cost sheets. Jobs 303 and 304 are still in process at the end of the month, and all applicable costs except factory overhead have been recorded on the related cost sheets. In addition to the materials and labor charged directly to the jobs, $8,400 of indirect materials and $13,700 of indirect labor were used during the month. The cost sheets for the four jobs entering production during the month are as follows, in summary form:

The Gourmand Cooking School runs short cooking courses at its small campus. Management has identified two cost drivers it uses in its budgeting and performance reports—the number of courses and the total number of students. For example, the school might run two courses in a month and have a total of 61 students enrolled in those two courses. Data concerning the company’s cost formulas appear below:

For example, administrative expenses should be $3,600 per month plus $44 per course plus $5 per student. The company’s sales should average $890 per student.

The company planned to run four courses with a total of 61 students; however, it actually ran four courses with a total of only 59 students. The actual operating results for September appear below:

Required:

Prepare a flexible budget performance report that shows both revenue and spending variances and activity variances for September. (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values.)

At the Joseph Biden Middle School in Down-the-Shore, Delaware, student reading comprehension was evaluated, both pre-test and post-test, bookending a pilot program intervention advocated by the district superintendent and board of education.

The vice-principal optimistically expected that the intervention would improve reading comprehension scores, whereas the principal pessimistically anticipated that the instrument confused students and scores dropped. Identify the mean average scores on the pre-test and post test instruments, and what the average change was across all participants reported in this sample. Test with 90% confidence that the claim that the intervention had an impact of some kind. State the hypotheses and the conclusions, both technically and contextually. Confirm the findings with the corresponding p-value and confidence interval.

The Business School at State University currently has three parking lots, each containing 155 spaces. Two hundred faculty members have been assigned to each lot. On a peak day, an average of 70% of all lot 1 parking sticker holders show up, an average of 72% of all lot 2 parking sticker holders show up, and an average of 74% of all lot 3 parking sticker holders show up.

a. Given the current situation, estimate the probability that on a peak day, at least one faculty member with a sticker will be unable to find a spot. Assume that the number who show up at each lot is independent of the number who show up at the other two lots. Compare two situations: (1) each person can park only in the lot assigned to him or her, and (2) each person can park in any of the lots (pooling). (Hint: Use the RISKBINOMIAL function.) If needed, round your answer to a whole percentage and if your answer is zero, enter "0".

b. Now suppose the numbers of people who show up at the three lots are highly correlated (correlation 0.9). How are the results different from those in part a? If needed, round your answer to a whole percentage.
