Help with 21 please
17-21: Use the following scenario to answer the questions that follow. A study was conducted examining the effectiveness of the drug teplizumab at delaying or preventing Type I diabetes. Out of n₁ = 38 people who took the drug, P = 42% of them developed diabetes. Out of n2 = 38 people who did not take the drug, p2 = 68% of them developed diabetes. Estimate at 99% confidence the difference pi - P2. 17. Find the value of z or t, whichever is appropriate. Sketch the appropriate bell curve. 11일을 1 - 0,01 = 0.995 2 005 √ P₁L1-P₁) + P₂ (1-6) ni n₂2 P1-P21Z.SE -аа 2-2.575 18. Calculate the standard error.
