Statistics 1. A running coach is researching how the pace of runners changes during the course of a race. a. He takes a simple random sample of 20 athletes running an 800m race. The 800m race consists of two laps round a 400m track. What statistical test should he perform to determine whether there is a difference between population average completion times for the first lap and the last lap? b. He takes another simple random sample of 20 athletes running a 1200m race. The 1200m race consists

Letting µ represent the mean composite satisfaction rating for the XYZ-Box‚ set up the null hypothesis H₀ and the alternative hypothesis H₀ needed if we wish to attempt to provide evidence supporting the claim that µ exceeds 42. H₀: µ ≤ 42 H₀: µ > 42 b. The random sample of 65 satisfaction ratings yields a sample mean of Ẋ = 42.954. Assuming that
