The line of regression of y on x is y = 13.6 - 0.8x and the
original data is published as follows:
x: 1
2 3
4
5
6
7
8
y: 14.3 9.5 11.2 11.0
10.4 8.6 8.1
9.6
Given that one of the values of y is misprinted state which
value of y is wrong and correct it
In the previous part summation of y was determined to be 80
and summation of xy was determined to be 326.4
