A researcher randomly chooses six fathers who have adult sons as well as records the fathers' and sons' heights to obtain the data below. Find out if sons are taller than their fathers at the a = 0.1 level of significance. The normal probability plot as well as boxplot point to that the differences are approximately normally distributed with no outliers.
Observation Height of father (inches) Height of son (inches)
1 73.6 77.9
2 67.7 66.5
3 74.9 75.8
4 65.9 64.4
5 72.2 76.0
6 68.5 66.4
Using the differences (father's height) - (son's height), what is your conclusion regarding H0?
A. Do not reject because t0 is less than - ta.
B. Reject H0 because t0 is less than - ta.
C. Reject H0 because t0 is greater than - ta.
D. Do not reject H0 because t0 is greater than - ta.
