In a clinical trial of a drug intended to help people stop smoking, 128 subjects were treated with the drug for 11 weeks, and 19 subjects experienced abdominal pain. If someone claims that more than 8% of the drug's users experience abdominal pain, that claim is supported with a hypothesis test conducted with a 0.05 significance level. Using 0.17 as an alternative value of p, the power of the test is 0.95
.
Interpret this value of the power of the test.
