the table shows the test scores and the sleep averages of several students.
test score (%) 88,75,76,92,96,94,83,90,99,65,77,88 ,82,83,94,97
average sleep (h) 7,6.5,6,7.5,8,7,6.5,8,8.5 5,7,9,8,8.5,8.5,9
(a)write the least squares regression equation that models the data. let x = the test score and y = average sleep.
(b)use the equation to determine the approximate test score of a student who sleeps an average of 8 h a night. i understand if you don't want to give me the answer but can you at least explain what i have to do.
