Question

For steps 3 and 7, only one of the rows is applicable, as it states. Green boxes are supposed to be rounded to 4 decimals and the blue boxes are supposed to be 2 or 3 depending on whether a T or Z table is appropriate

The two samples below are independent from Normal populations with equal variances. Sample 1 Sample 2: 16 12 353 209 8,027 4,190 x2) 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 itf or Step 4 Step 5 Step 6 Step 7 HO Fill in the row 49 if the Z table is appropriate. 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 Endpoint

Explanation / Answer

Hypothesis is one tailed

Reject H0 if test statistics t is greater than 1.3147

t = 0.5975

Failed to reject H0

p-value = 0.2777
