Is there convincing evidence that the mean calorie intake for teens who typically eat fast food is greater than the mean intake for those who don't by more than 150 calories per day? (Test the relevant
hypotheses using a significance level of a = 0.05. Use u, for teens who typically eat fast food and u, for teens who don't typically eat fast food.)
State the appropriate null and alternative hypotheses.

State the conclusion in the problem context.
We fail to reject Ho. There is not convincing evidence that the mean calorie intake for teens who typically eat fast food is greater than the mean intake for those who don't by more than 150 calories
per day.
We reject H.: There is not convincing evidence that the mean calorie intake for teens who typically eat fast food is greater than the mean intake for those who don't by more than 150 calories per
day.
O We fail to reject Ho. There is convincing evidence that the mean calorie intake for teens who typically eat fast food is greater than the mean intake for those who don't by more than 150 calories per
day.
We reject Ho. There is convincing evidence that the mean calorie intake for teens who typically eat fast food is greater than the mean intake for those who don't by more than 150 calories per day.
