Solution
For this case we have the following data:
x: 75,76, 91, 65,48,75,85,62,51,80,94,43
y: 69, 88, 101, 63, 59, 82, 86, 67, 56, 84, 105, 44
We can use the ordinaly least squares OLS in order to find the best regression line in the form:
y= mx+b
After the procedure we have the following line:
y= 1.0607x + 0.6442
Rounded with 3 decimals we got:
y= 1.061x + 0.644
