We want to test the claim that people are taller in the morningthan in the evening. Morning height and evening height weremeasured for 30 randomly selected adults and the difference(morning height) − (evening height) for each adult was recorded inthe table below. Use this data to test the claim that onaverage people are taller in the morning than in the evening.Test this claim at the 0.01 significance level.

(a) In mathematical notation, the claim is which of the following? μ = 0 μ ≠ 0   μ > 0 μ < 0 (b) What is the test statistic? Round your answer to 2decimal places. t x = (c) Use software to get the P-value of the test statistic.Round to 4 decimal places. P-value = (d) What is the conclusion regarding the null hypothesis? reject H0fail to rejectH0     (e) Choose the appropriate concluding statement. The data supports the claim that on average people aretaller in the morning than in the evening. There is not enough data to support the claim that onaverage people are taller in the morning than in theevening.    We reject the claim that on average people are tallerin the morning than in the evening.
