During the second round of the 1989 U.S. Open golf tournament, four golfers scored a hole in one on the sixth hole. The odds of a professional golfer making a hole in one are estimated to be 3,708 to 1, so the probability is 1/3,709. There were 155 golfers participating in the second round that day. Estimate the probability that four golfers would score a hole in one on the sixth hole.
Chapter 9 3/28/17 in-class notes Hypothesis Tests Testing hypotheses: testing the validity of a claim/assumption about value of a population parameter (µ or p) Null (H0) and Alternative (H a hypotheses Two types of error in conclusion: Type I and Type II, with specific probabilities/risks Hypothesis testing regarding the population mean (same as Ch 8) o Use the z distribution in known cases o Use the t distribution in unknown cases Hypothesis testing regarding the population proportion o Always use the z distribution Hypothesis testing can be used to determine whether a statement/claim about the value of a population parameter (µ or p) should or should not be rejected based on x
