I need help with - Should the null hypothesis be rejected? - at the very bottom. Thank you!
To test the belief that sons are taller than their fathers, a student randomly selects 13 fathers who have adult male children. She records the height of both the father and son in inches and obtains the following data. Are sons taller than their fathers? Use the alpha α = 0.025 level of significance.
Note: A normal probability plot and boxplot of the data indicate that the differences are approximately normally distributed with no outliers.

Which conditions must be met by the sample for this test? Select all that apply.
A. The sample size must be large.
B. The differences are normally distributed or the sample size is large.
C. The sampling method results in an independent sample.
D. The sample size is no more than 5% of the population size.
E. The sampling method results in a dependent sample.
Let di=Xi−Yi.
Write the hypotheses for the test.
H0: ▼μd=0
H1: ▼μd<0
Calculate the test statistic.
t0=0.00
(Round to two decimal places as needed.)
Calculate the P-value.
P-value=0.5
(Round to three decimal places as needed.)

A researcher randomly selects 6 fathers who have adult sons and records the fathers' and sons' heights to obtain the data shown in the table below. Test the claim that sons are taller than their fathers at the alpha equals 0.10α=0.10 level of significance. The normal probability plot and boxplot indicate that the differences are approximately normally distributed with no outliers so the use of a paired t-test is reasonable.
