Use the following information when answering questions 4) -> 7) below. To compare two populations, you take a sample from each and observe data with following summary statistics (Two Population worksheet): Population 1: n₁ = 31 Population 2 n₂ = 41 S₁ = 4 x₁ = 17 S₂ = 3 x₂ = 12 versus Ha: o> o2 using a = 0.05, what is the 12 4) In a test of the hypothesis Ho: o ≤o critical value for the hypothesis test? A) 1.79 B) 2.01 C) 1.65 D) 1.74 E) 1.94 5) In a test of the hypothesis Ho: o2 o2 versus Ha: o> o2 using a = 0.05, what is the p-value for the hypothesis test? A) p-value < 0.01 B) 0.01 <p-value < 0.025 C) 0.025 <p-value < 0.05 D) 0.05 <p-value < 0.10 E) p-value > 0.10 6) In a test of the hypothesis Ho: H₁-H2 ≥ 7 versus Ha: H₁ H₂ < 7 using a = 0.05, what is the Test Statistic for the hypothesis test? it is the LSD A) -1.65 B) -2.33 C) -1.833 D) -1.96 E) -2.093 7) In a test of the hypothesis Ho: ₁ - 2 ≥ 7 versus Ha: H₁ - H₂2 < 7 using a = 0.05, what is the critical lue for the hypothesis test?
