Given the following values of income and consumption
x | 20 | 11 | 15 | 10 | 17 | 19 | |
y | 5 | 15 | 14 | 17 | 8 | 9 |
a) Find the covariance
b) Find and explain the correlation
c) Determine the equation of least squares line
d) Find predicted values of Y for X = 16 & 25
from the table we calculate the mean and the sum of squares
let "m" be the slow and "n" be the Y intercept
