The data below displays heights (in inches) of a random sample of students and their parent of the same sex. Student (s) 70 65 68 63 72 71 Parent (p) 65 67 64 63 70 66 Difference (s-p) 5 -2 4 0 2 5 The mean for the difference between student and parent heights is   = 2.33 and the sample standard deviation for the difference between student and parent heights is sD = 2.88.   We can assume the distribution of the differences is Normal. The p-value for this hypothesis test is 0.0218.  At a 0.05 significance level, what conclusion can you make?
