13) A researcher randomly selects 6 fathers who have adult sons and records the fathers\' and sons\' heights to obtain the data below. Determine if sons are taller than their fathers at the a = 0.1 level of significance. The normal probability plot and boxplot indicate that the differences are approximately normally distributed with no outliers.

(a) Using the differences (fathers height) - (sons heights), what is your conclusion regarding H0?

A) Reject H0 because t0 is less than -ta.

B) Reject H0 because t0 is greater than -ta

C) Do not reject H0 because t0 is less than -ta

D) Do not reject H0 because t0 is greater than -ta

Solution

C) Do not reject H0 because t0 is less than -ta
