Effect of larger sample size The study described in Exercise 33 is repeated with a large sample of 1000 subjects Assume that the sample mean is once again 0 5 pound and the sample standard deviation is once again 4 pounds a Find the t statistic for testing Ho 0 versus H 0 Is the value o the t statistic greater than or less than the value obtained with a smaller sample of 100 b Find the P value for testing Ho 0 versus H 0 Can you conclude that the diet produces a mean weight loss that is greater than 0 Use the a 0 05 level of significance d Explain why the mean weight loss is not of practical significance even though the results are statistically significant at the 0 05 level
