Given are the grades of 10 students for prelim and midterm period in Statistics. Prelim (X) 75 70 65 90 85 85 80 70 65 90 Midterm (Y) 80 75 65 95 90 85 90 75 70 90 Estimate the midterm grade of a student whose prelim grade is 95. Select the correct response: 98.49 94.10 none of the choices 91.40 94.89

However, the data provided is incomplete. We only have 9 pairs of grades, but we are told there are 10 students. Without the complete data, we cannot accurately estimate the midterm grade of a student whose prelim grade is not provided. Show more…

A research was made of the midterm and final scores in a large course, with the following results: average midterm score = 60, SD = 15; average final score = 50, SD = 20, r = 0.60. The scatter diagram was football-shaped. For each student, the midterm score was predicted from the final score using a regression line. About what percentage of students score below 75 on the midterm? Select one: a. 88%. b. 90%. c. 84%. d. 92%. e. 86%.

The grades on a statistics exam for a sample of students are as follows: Stem | Leaf 3 | 68 4 | 1278 5 | 156789 6 | 122457888 7 | 1156799 8 | 1246 9 | 14 If A+ = 90%-100% A = 80%-89% B+ = 75%-79% B = 70%-74% C+ = 65%-69% C = 60%-64% D+ = 55%-59% D = 50%-54% F = 0-49% What is the most common letter grade earned?

In a large statistics class, the correlation between midterm scores and final scores is found to be nearly 0.50 , every term. The scatter diagrams are football-shaped. Predict the percentile rank on the final for a student whose percentile rank on the midterm is $\begin{array} { l l l l } { \text { (a) } 5 \% } & { \text { (b) } 80 \% } & { \text { (c) } 50 \% } & { \text { (d) unknown } } \end{array}$
