Question
The two samples below are independent from Normal populations with equal variances. Sample 1 Sample 2: 38 10 3,200 470 E(x^2)- (x^2)- 325,000 46,700 Question 1A Can you see from the data that 1 > 2 at a: 0.1? State the hypothesis in terms of 1-2. Step 1: HO: Ha: Step 2: Step 3: Fill in row 35 if the hypothesis is one tailed. Reject HO if Fill in row 39 if the hypothesis is two tailed. The smaller number must be typed first. Reject HO if or Step 4: Step 5: Step 6: Step 7: HO Fill in the row 49 if the Z table is appropri P-value Fill in the row 53 if the t table is appropriate. The lower boundary must go on the left and the upper boundary on the right. P-value Question 1B Construct a 99% confidence interval for the difference in population means. State the CI, in terms of 2-1. Lower Endpoint Upper EndpointExplanation / Answer
Reject H0 if t is greater than 1.7340
t = 1.358699087
Failed to reject H0
p-value = 0.0955
