In clinical trials, 77 out of 610 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 larger than 10%. Use a 0.01 significance level to test the claim. Claim: which corresponds to Opposite: which corresponds to The test is: The test statistic is: The p-value is: Based on this we: Conclusion There appear to be enough evidence to support the claim that the proportion of patients taking Lipitor who experience flu-like symptoms is larger than 10%.
Explanation / Answer
The statistical software output for this problem is:
One sample proportion summary hypothesis test:
p : Proportion of successes
H0 : p = 0.1
HA : p > 0.1
Hypothesis test results:
Hence,
Claim: p > 0.10 which corresponds to H1: p > 0.10
Opposite: p < 0.10 which corresponds to H0: p < 0.10
Right Tailed Test
Test statistic = 2.16
p - Value = 0.0154
