Question
To test the belief that sons are taller than their fathers, a student randomly selects 6 fathers who have adult male children. She records the height of both the father and son in inches and obtains the accompanying data. Are sons taller than their fathers? Use the alpha = 0.1 level of significance. Note that a normal probability plot and boxplot of the data indicate that the differences are approximately normally distributed with no outliers. Click the Icon to view the height data. Choose the correct null and alternative hypotheses below Let d_i = Y_i - X_i. H_0: mu_d = 0 H_1: mu_d > 0 H_0: mu_d notequalto 0 H_1: mu_d = 0 H_0: mu_d 0 H_0: mu_d > 0 H_1: mu_dExplanation / Answer
option A is correct
from above p value =0.3401
do not reject Ho: there is not sufficient...... option A
