What impact does fast-food consumption have on various dietary and health characteristics? A research article reported the accompanying summary statistics on daily calorie intake for a representative sample of teens who do not typically eat fast food and a representative sample of teens who do eat fast food. Scenario 5 Sample Sample Sample Size Mean SD Do not eat fast 666 food 2257 1514 Eat fast 415 food 2636 1139 For hypothesis testing, state your hypotheses, using Meat Inot eat, find the test statistic, find the P- value, and interpret your result. 1. Construct a C-level confidence interval estimate of the difference in mean daily calorie intake for teens who do eat fast food on a typical day and those who do not, where C is 80%, 90%, 99%. 2. 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 200 calories per day? Test the relevant hypotheses using a significance level of 0.05 3. 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 400 calories per day? Test the relevant hypotheses using a significance level of 0.01.

Transcribed Image Text:What impact does fast-food consumption have on
various dietary and health characteristics? A research
article reported the accompanying summary statistics
on daily calorie intake for a representative sample of
teens who do not typically eat fast food and a

For hypothesis testing, state your hypotheses, using
Heat
Unot eat, find the test statistic, find the P-
value, and interpret your result.
1. Construct a C-level confidence interval
estimate of the difference in mean daily
calorie intake for teens who do eat fast
food on a typical day and those who do not,
where C is 80%, 90%, 99%.
2. 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 200
calories per day? Test the relevant
hypotheses using a significance level of
0.05
3. 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 400
calories per day? Test the relevant
hypotheses using a significance level of
0.01.
