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 p₁ - p2. 17. Find the value of z or t, whichever is appropriate. Sketch the appropriate bell curve. P 12 SE 18. Calculate the standard error. Write the formula with the correct values inserted.

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 p₁ - p2.
17. Find the value of z or t, whichever is appropriate. Sketch the appropriate bell curve.
PP 12 SE
18. Calculate the standard error. Write the formula with the correct values inserted.
19. Calculate the margin of error. Write the formula with the correct values inserted.
20. Calculate the interval. Write the formula with the correct values inserted.
21. Based on your interval, is it plausible the drug has no impact on developing
diabetes? (The drug would have no impact if p₁=p2).
