The drug Lipitor is meant to reduce total cholesterol. In clinical trials, 362 out of 584 patients taking 10mg of Lipitor daily complained of flu-like symptoms. A patient advocacy group claims that the proportion of patients taking Lipitor who experience flu-like symptoms is at least 70%. Use a 0.10 significance level to test the claim. Claim: Select an answer u ≥ 0.7 u = 0.7 p = 0.7 u ≤ 0.7 p > 0.7 u > 0.7 u ≠ 0.7 p < 0.7 p ≠ 0.7 p ≥ 0.7 p ≤ 0.7 u < 0.7 which corresponds to Select an answer H0: p = 0.7 H1: p > 0.7 H1: p ≠ 0.7 H0: p ≤ 0.7 H0: p ≠ 0.7 H1: p < 0.7 H0: u ≥ 0.7 Opposite: Select an answer p < 0.7 u ≤ 0.7 p = 0.7 u ≥ 0.7 u = 0.7 u > 0.7 p ≤ 0.7 u < 0.7 p > 0.7 p ≠ 0.7 p ≥ 0.7 u ≠ 0.7 which corresponds to Select an answer H1: p < 0.7 H1: p > 0.7 H0: p ≠ 0.7 H0: p = 0.7 H0: p ≤ 0.7 H0: u ≥ 0.7 H1: p ≠ 0.7

Claim: Select an answer u ≥ 0.7 u = 0.7 p = 0.7 u ≤ 0.7 p > 0.7 u > 0.7 u ≠ 0.7 p < 0.7 p ≠ 0.7 p ≥ 0.7 p ≤ 0.7 u < 0.7 which corresponds to Select an answer H0: p = 0.7 H1: p > 0.7 H1: p ≠ 0.7 H0: p ≤ 0.7 H0: p ≠ 0.7 H1: p < 0.7 H0: u ≥ 0.7
Opposite: Select an answer p < 0.7 u ≤ 0.7 p = 0.7 u ≥ 0.7 u = 0.7 u > 0.7 p ≤ 0.7 u < 0.7 p > 0.7 p ≠ 0.7 p ≥ 0.7 u ≠ 0.7 which corresponds to Select an answer H1: p < 0.7 H1: p > 0.7 H0: p ≠ 0.7 H0: p = 0.7 H0: p ≤ 0.7 H0: u ≥ 0.7 H1: p ≠ 0.7
The test is: Select an answer right-tailed two-tailed left-tailed
The test statistic is: (to 2 decimals)
The p-value is: (to 4 decimals)
Based on this we: Select an answer Fail to reject the null hypothesis Reject the null hypothesis
Conclusion There Select an answer does does not appear to be enough evidence to support the claim that the proportion of patients taking Lipitor who experience flu-like symptoms is at least 70%.
