2. A study for adverse reactions assigned adults at random to one of two common pain relievers (ibuprofen and acetaminophen). It was found that out of 733 adults who were administered ibuprofen, 103 of them experienced an adverse reaction, and out of 732 adults who were administered acetaminophen, 85 of them experienced an adverse reaction. Let p1 denote the proportion of adults who experience an adverse reaction when taking ibuprofen and let p2 denote the proportion of adults who experience an adverse reaction when taking acetaminophen. Suppose we want to answer the following questions. i) Test, at the 3% level of significance, whether the proportion of adults who experience an adverse reaction when taking ibuprofen is greater than the proportion of adults who experience an adverse reaction when taking acetaminophen. ii) Calculate the 97% confidence interval for P1 – P2- The table below provides the information needed to perform the hypothesis test:

Question

Transcribed Image Text:d. At the 3% level of significance, does the p-value support the claim that the proportion of adults who experience an
adverse reaction when taking ibuprofen is greater than the proportion of adults who experience an adverse reaction
when taking acetaminophen? Explain.
O No, since the p-value
0.0813 > 0.03
O No, since the p-value
0.1283 > 0.03
O No, since the p-value
0.002 < 0.03
Yes, since the p-value = 0.0813 > 0.03

Transcribed Image Text:2. A study for adverse reactions assigned adults at random to one of two common pain relievers (ibuprofen and
acetaminophen). It was found that out of 733 adults who were administered ibuprofen, 103 of them experienced an
adverse reaction, and out of 732 adults who were administered acetaminophen, 85 of them experienced an adverse

denote the proportion of adults who experience an adverse reaction when taking acetaminophen. Suppose we want to
answer the following questions.
i) Test, at the 3% level of significance, whether the proportion of adults who experience an adverse reaction when taking
ibuprofen is greater than the proportion of adults who experience an adverse reaction when taking acetaminophen.
ii) Calculate the 97% confidence interval for p1
