Run a regression analysis on the following data set, where yy is the final grade in a math class and xx is the average number of hours the student spent working on math each week.

hours/week x	Grade y
4	59.6
7	67.8
7	68.8
11	78.4
12	68.8
14	79.6
16	88.4
18	92.2
18	100
20	100

State the regression equation y=m⋅x+by=m⋅x+b, with constants accurate to two decimal places.
$y=4.11x+-33.14$y=4.11x+−33.14Incorrecty=2.5⋅x+48.61y=2.5⋅x+48.61

What is the predicted value for the final grade when a student spends an average of 7 hours each week on math?
