A teacher wanted to predict a student's score on the linear correlation test based on the number of hours the student studied. The teacher discovered that test grades y are related to the number of study hours x. Suppose that the equation of the regression line is y = 8x + 4. If a student studied for 11 hours, what grade would the teacher predict? a) 84 b) 88 c) 92

Step 1
Step 1: Given the regression line equation y = 8x + 4 and x = 11 hours, we need to substitute x = 11 into the equation to find the predicted grade. Show more…

8 students were asked, how many hours they were studying before the test, and what grade they got. a) Find the equation of the regression line for the data below. Write your answer in form of y=ax+b, do not use the space bar, round the coefficients to the nearest tenth place. b) Find the correlation coefficient, round the coefficient to the nearest hundredth place. X, hours studying Y, test grade 12 85 4 60 3 45 14 92 2 54 9 80 8 72 11 65

A mathematics teacher wanted to see the correlation between test scores and homework. The homework grade (x) and test grade (y) are given in the accompanying table. Write the linear regression equation that represents this set of data, rounding all coefficients to the nearest tenth. Using this equation, find the projected test grade, to the nearest integer, for a student with a homework grade of 54. Homework Grade (x) | Test Grade (y) 87 | 83 83 | 83 54 | 41 56 | 58 65 | 57 72 | 63 89 | 79 79 | 71

A student at Joliet Junior College conducted a survey of 20 randomly selected full-time students to determine the relation between the number of hours of video game playing each week, $x,$ and grade-point average, $y .$ She found that a linear relation exists between the two variables. The least-squares regression line that describes this relation is $\hat{y}=-0.0526 x+2.9342$ (a) Predict the grade-point average of a student who plays video games 8 hours per weck. (b) Interpret the slope. (c) If appropriate, interpret the $y$ -intercept. (d) A student who plays video games 7 hours per week has a grade-point average of $2.68 .$ Is this student's grade-point average above or below average among all students who play video games 7 hours per week?
