Construct a 90% confidence interval for (u1- u2)

For some reason I am getting it wrong, (-19.404) (-1.196), round to 3 decimal places pease. Explain in details please, I need to study the calculations step by step.

Independent random samples from approximately normal populations produced the results shown below. Complete parts a and b. Full data set Sample 1 Sample 2 49 28 36 35 43 43 21 70 58 53 53 58 36 56 52 28 36 39 45 60 A. HO: H1 - 12 = 0, Ha: H1 - 12 # 0 OB. HO: H1 - H2 = 0, Ha: H1 - H2 0 Now find the test statistic. t= - 1.90 (Round to two decimal places as needed.) Find the p-value. p-value = 0.08 (Round to two decimal places as needed.) Choose the correct conclusion below. O A. Do not reject Ho. There is sufficient evidence that the means differ. O B. Reject Ho. There is insufficient evidence that the means differ. C. Reject Ho.
