5. An accounting firm is interested in estimating the error rate in a compliance audit it isconducting. The population contains 828 claims, and the firm audits an SRS of 85 ofthose claims. In each of the 85 sampled claims, 215 fields are checked for errors. Oneclaim has errors in 4 of the 215 fields, 1 claim has three errors, 4 claims have twoerrors, 22 claims have one error, and the remaining 57 claims have no errors.a. Treating the claims as psu's and the observations for each field as ssu's,estimate the error rate for all 828 claims. Give a standard error for yourestimate.b. Estimate the total number of errors in the 828 claims. Give a standard error forthis estimate.c. Suppose that, instead of taking a cluster sample, the firm takes an SRS of 85 x215=18,275 fields from the 178,020 fields in the population. If the estimatederror rate from the SRS is the same as in part (a), what will be the estimatedvariance under SRS? How does this compare with the estimated variance frompart (a)?

Answer the following question.
10. The most common species of sweat bees are green, red, and yellow. For each color, we select a sample of 100 of bees of this color and record their length (in inches). We then create 3 data sets of 100 observations each, called "green", "red" and "yellow". Below are the boxplots and histograms for these data sets. The labels of the variables are missing from the histograms, but are included in the boxplots. Our task is to identify the missing labels. Which one of the following statements is correct?

3. A mathematics placement test is given to all entering freshmen at a small college. A student who receives a grade below 35 is denied admission to the regular mathematics course and placed in a remedial class. The placement test scores and the final grades for 20 students who took the regular course were recorded as follows: Placement Test Course Grade | Placement Test | Course Grade 50 53 90 54 35 35 41 80 60 91 61 48 40 56 60 71 55 68 60 71 65 36 40 47 35 11 55 53 60 70 50 68 90 79 65 57 35 59 50 79 (a) Plot a scatter diagram. (b) Find the equation of the regression line to predict course grades from placement test scores. (c) Graph the line on the scatter diagram (d) If 60 is the minimum passing grade, below which placement test score should students in the future be denied admission to this course?

3. Travelers who have no intention of showing up often fail to cancel their hotel reservations in a timely manner. These travelers are known, in the parlance of the hospitality trade, as "no-shows". To protect against no-shows and late cancellations, hotels invariably overbook rooms. A recent study examined the problems of over-booking rooms in the hotel industry. The following data, extracted from the study represent the daily numbers of late cancellations and no-shows for a random sample of 10 days at a hotel: 18, 16, 16, 16, 14, 18, 16, 18, 14, 19. c) Count the number of measurements that actually fall within the interval(-28, +2s) and express the interval count as a percentage of total number of measurements. at least 75% 100% 68% 95%
