Question

Find the linear regression line for the following table of values. You will need to use a calculator, spreadsheet, or statistical software. Enter your answer in the form y=mx+b, with m and b both rounded to two decimal places. x y 3 6.03 4 9.65 5 11.49 6 11.57 7 12.96 8 14.97 9 16.31 10 17.43 11 18.55    statistics

Answer 1

Using the above data and the calculator

= 7

= 13.217777777778

= 63

= 118.96​

= 501

= 1701.3544

= 919.18

n = 9

So SSxx = 60

SSyy = 128.96755555556

SSxy = 86.46

So m = 1.441

and b= = 3.1308

So linear regression line is y=3.1308+1.441x
