The mean weight of statistics books in the U.S. is 140 pounds with a standard deviation of 20 lbs. We sure pack a lot of stuff in these books!!! You select 400 books at random and measured their weight and found the mean for this sample was 137 lbs. Using a level of significance of 0.05, test the hypothesis that the true weight is 140 lb.

An experiment was conducted to test the effect of a new dietary supplement for weight loss. Ten men and 10 women were given the supplement daily for a month, then the amount of weight each person lost was determined. A significance test was conducted at the ? = 0.05 level for the difference in the means of the number of pounds lost between men and women. The test resulted in t = 2.178 and p = 0.03. If the alternative...

Big babies: The National Health Statistics Reports described a study in which a sample of 322 one-year-old baby boys were weighed. Their mean weight was 25.1 pounds with standard deviation 5.3 pounds. A pediatrician claims that the mean weight of one-year-old boys is greater than 25 pounds. Do the data provide convincing evidence that the pediatrician's claim is true? Use the a-0.05 level of significance and the P-value method with the TI-84 Plus calculator al Part: 0/4 Part 1 of...
