A researcher, working for a large pharmaceutical company, is interested in testing the claim that less than 24% of people who take a new sinus medication receive symptom relief in less than 15 minutes. To test this claim, the researcher collects the following data on a sample of 500 adults and 110 of them receive symptom relief in less than 15 minutes after taking the medication. The following is the data from this study: Sample size =500 adults The alternative hypothesis is Ha:p<0.24 The test statistic is calculated as z0=−1.05. Find and interpret the p− value for this hypothesis test. Use the curve below to help visualize your answer. Select the appropriate test by dragging the blue point to a right-, left- or two-tailed diagram, then set the test statistic on the x-axis to find the p-value. Based on the p-value
