Below you can find father and sons heights in inches.
FATHER'S HEIGHTS (x) : 63 67 64 60 65 67 59 60
SON'S HEIGHTS (y) : 61.6 66.7 65.3 61.0 65.4 67.4 60.9 63.1
1. calculate the correlation coefficient between x and y
2. Test if there is a linear correlation between x and y under a significance level of 0.01.
3. find regression line between x and y if linear correlation exists. Predict sons height if father is 66 inches.
