1. Practical Significance When testing the claim that the mean amount lost on a diet is greater than 0 lb, we use sample results showing that 10,000 people lost amounts with a mean of 0.1 lb. Also, the sample standard deviation is 0.8 lb. The hypothesis test results include a test statistic of t 5 12.500 and a P-value of 0.0000 (rounded to four decimal places). Is the mean weight loss statistically significant? Does the mean weight loss suggest that this diet is practical? Should it be recommended?
