Hello I need help with this question
HW 10 hyp test: Problem 10 (1 point) Two independent samples have been selected, 74 observations from population 1 and 95 observations from population 2. The sample means have been calculated to be ₁ = 11.7 and 2 = 13.4. From previous experience with these populations, it is known that the variances are o = 35 and o2 = 36. (a) Find (1-2)* answer: (b) Determine the rejection region for the test of Ho : (µ₁ − µ₂) = 2.71 and Ha : (µ₁ − µ2) > 2.71 Use a = 0.04. 2 > (c) Compute the test statistic. 2 = The final conclustion is O A. We can reject the null hypothesis that (μ₁ - M₂) = 2.71 and accept that (µ₁ − µ₂) > 2.71. OB. There is not sufficient evidence to reject the null hypothesis that (μ₁ −μ₂) = 2.71. (d) Construct a 96 % confidence interval for (μ₁ −μ2). ≤ (μ1 −μ₂) ≤
