4. Mr. V has finished grading and recording all of the scores for a difficult exam. Here are the scores: 53, 94, 90, 77, 83, 98, 75, 82, 94, 79, 71, 76, 90, 87, 71, 72, 71, 86, 96, 94, 82, 70, 81, 88, 84, 91, 90, 90, 90, 65, 100, 89. He now needs to arrange the scores to determine whether the exam should be curved. In order to do this, he constructs a stem-and-leaf plot.
5. Mark’s class just took the admission test for business school and averaged 87.05. Chapter 10 Data Set 2 contains the population of scores for the 10 other classes in Mark’s university.

Problem #1: Consider the below matrix A, which you can copy and paste directly into Matlab. The matrix contains 3 columns. The first column consists of Test #1 marks, the second column is Test # 2 marks, and the third column is final exam marks for a large linear algebra course. Each row represents a particular student.A = [36 45 75 81 59 73 77 73 73 65 72 78 65 55 83 73 57 78 84 31 60 83...
ofessor believes that the final examination scores in statistics distributed. A sample of 40 final s sample of 40 final scores has been taken. You are given the sample below. The mean of the scores is 83.1, and the standar the scores is 83.1, and the standard deviation is 10.43. 56 63 65 68 72 72 73 75 77 78 78 79 80 80 80 80 80 80 81 81 82 84 84 86 86 87 88 90 90 92...
Student stress at final exam time comes partly from the uncertainty of grades and the consequences of those grades. Can knowledge of a midterm grade be used to predict a final exam grade? A random sample of 200 BCOM students from recent years was taken and their percentage grades on assignments, midterm exam, and final exam were recorded. Let’s examine the ability of midterm and assignment grades to predict final exam grades. The data are shown here: Assignment Midterm FinalExam...
PLEASE SHOW ME HOW TO DO THIS.... For the Excel Data Set please find and report for Test 1 and Test 2 the Mean, SD, and the tolerance levels for both for which there would be any outliers (i.e., the value for which a score must be less than to be consider an outlier and the value for which a number must greater than to be considered an outlier. See picture Performance Data Group 1 1 1 1 Test 2...

Use the Grouped Distribution method for the following exercise (see Self-Test 2-4 for detailed instructions), rounding each answer to the nearest whole number. Using the frequency distribution below (scores on a statistics exam taken by 80 students), determine:ion 1 of the preliminary test (scores on a statistics exam taken by 80 students), determine: 68 84 75 82 68 90 62 88 76 93 73 79 88 73 60 93 71 59 85 75 61 65 75 87 74 62 95...
