D—nc‘m 9—069: 9—059: D—no‘m You are testingthe hypothesis that the mean commuting time to the IUPUI campus is less
than 20 minutes. The null and alternative hypothesis statements for this test are: Ho: 0320 H1: u>20
Ho: “<20 H1: 0220
Ho: 0220 H1: ”<20
Hg: “>20 H1: 0520 You are testing the hypothesis that the mean student commuting distance to the IUPUI

Ho: u> 10 H1: 01:10 You are testingthe hypothesis that more than 75% ofdrivers on a freeway violate the

Ho: 11 = 0.85 H1: r: at 0.85
Ho: 11 s 0.85 H1: TE > 0.85 Hg: 11 2 0.85 H1: 1': < 0.85
