Question 1023907: Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line. (The pair of variables have a significant correlation.) Then use the regression equation to predict the value of y for each of the given x-values, if meaningful. The number of hours 6 students spent for a test and their scores on that test are shown below.
Hours spent studying, x: 0,2,3,3,4,5
Test scores, y:41,46,49,45,65,69
a) x= 2 hours
b) x= 2.5 hours
c) x= 15 hours
d) x= 3.5 hours
Find the regression equation.

Hi
x y
0 41
2 46
3 49
3 45
4 65
5 69
y = 5.8315x + 35.978 (Excel scatter plot...Format: Trendline/formula
a) x= 2 hours y = 5.8315(2) + 35.978
b) x= 2.5 hours y = 5.8315(2.5) + 35.978
c) x= 15 hours y = 5.8315(15) + 35.978
d) x= 3.5 hours y = 5.8315(3.5) + 35.978
