Casey is a statistics student who is conducting a one-sample z‑test for a population proportion p using a significance level of a=. Her null (H0) and alternative (Ha) hypotheses are H0:p=0.094Ha:p≠0.094   The standardized test statistic is z = 1.40. What is the P-value of the test?  P-value =

A headache medicine is tested on an experimental group of 50 patients who have headaches. Out of these people, 37 of them say they felt better when taking the medicine. A fake pill (placebo) is given to 50 different patients, of whom 27 say they felt better after taking the "medicine". Is this enough evidence to show that a higher percentage of people in the experimental group were cured, compared to the control group? (Use a = .01) Type of Test: Hypotheses: Test Statistic: P-value: Decision: XC. In a sentence, what can be said about the medicine?

Conduct the proper test to determine whether a cold medicine improves symptoms (lower scores correspond to less severe symptoms).
