It is claimed that only 5% of professional golfers are left-handed. Believing this claimed value is incorrect, a researcher surveys a large random sample of professional golfers and finds that the percentage who are left-handed is 3%. When a hypothesis test is conducted at a significance (or alpha) level of 0.01, the p-value is found to be 0.02. What decision should the researcher make based on the results of the hypothesis test? A. The null hypothesis should be rejected because 0.02 is less than 0.05. B. The null hypothesis should be rejected because 0.02 is less than 0.03. C. The null hypothesis should be rejected because 0.02 is greater than 0.01. D. The null hypothesis should be rejected because 0.03 is greater than 0.01. E. The null hypothesis should not be rejected.
