Hot dogs and calories-hot dogs and sodium

1. Hot dogs and calories. Consumers increasingly make food purchases based on nutrition values. In the July 2007 issue, Consumer Reports examined the calorie content of two kinds of hot dogs: meat (usually a mixture of pork, turkey, and chicken) and all beef. The researchers purchased samples of several dif- ferent brands. The meat hot dogs averaged 111.7 calories, compared to 135.4 for the beef hot dogs. A test of the null hypothesis that there's no difference in mean calorie content yields a P-value of 0.124. What would you conclude?

2. Hot dogs and sodium. The Consumer Reports article de- scribed in Exercise 25 also listed the sodium content (in mg) for the various hot dogs tested. A test of the null hypothesis that beef hot dogs and meat hot dogs don't differ in the mean amounts of sodium yields a P-value of 0.110. What would you conclude?
