to provide evidence supporting he claim that the mean composite satisfaction rating for the XYZ-Box exceeds 42. a. 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 σ equals 2.64 use critical
