Question 11
6/6 points
What impact does fast food consumption have on various dietary and health characteristics? An article reported the accompanying summary data on daily calorie intake both for a sample of teens who said they did not typically eat fast food and another sample of teens who said they did usually eat fast food. Does this data provide strong evidence for concluding that true average calorie intake for those who typically eats fast food exceeds by more than 200 calories per day the true average intake for those who don't typically eat fast food? Investigate carrying out a test of the hypothesis at a significance level of approximately 0.05.
