Seventy-three successes were observed in a random sample of n = 120 observations from a binomial population. You wish to show that p > 0.5 USE SALT Calculate the appropriate test statistic. (Round your answer to two decimal places.) Z= Calculate the p-value. (Round your answer to four decimal places.) p-value = Do the conclusions based on a fixed rejection region of z> 1.645 agree with those found using the p-value approach at a = 0.05? O Yes, both approaches produce the same conclusion. O No, the p-value approach rejects the null hypothesis when the fixed rejection region approach fails to reject the null hypothesis. O No, the fixed rejection region approach rejects the null hypothesis when the p-value approach fails to reject the null hypothesis. Should they? O Yes O No
