Dietary guidelines recommend that most people should eat at least seven servings of fruits and vegetables each day. Yet, research suggests that few Americans do. Researchers suspect that lack of education may be partly to blame. To investigate, you survey 100 people and ask them about their education level and fruit and vegetable intake. Respondents report having 12.5 years of education and eating 4.5 servings of fruits and vegetables a day, on average. The standard deviations for education and fruit and vegetable consumption are 1.5 years and 2 servings, respectively. The correlation (r) between education and fruit and vegetable consumption is .18.

a) Calculate and interpret the slope.

b) Calculate and interpret the intercept.

c) Calculate and interpret the coefficient of determination.

d) Estimate the equation of the regression line that best describes the relationship between education and fruit and vegetable consumption.

e) Calculate the daily fruit and vegetable consumption for someone who has 16 years of education.

Overview Most doctors would probably agree that a Mediterranean diet, rich in vegetables, fruits, and grains, is healthier than a high-saturated fat diet. Indeed, previous research has found that the diet can lower risk of heart disease. However, there is still considerable uncertainty about whether the Mediterranean diet is superior to a low-fat diet recommended by the American Heart Association. This study is the first to compare these two diets. The subjects, 605 survivors of a heart attack, were randomly...

Helathcare econ please provide insight and explain Many experts recommend that people get at least 30 minutes of vigorous exercise three to five times a week; however, actual participation in exercise is less than the amount (a) needed or (b) demanded? Why do most college students get more exercise in summer than in winter?

Break-Even Analysis Most people intuitively understand that you ‘must at least break-even” and that you must go beyond break-even to earn a profit. For this exercise, create a hypothetical math problem scenario (word problem!) to demonstrate the calculation of break-even point. Set up the scenario and explain the calculation. Using that example, explain what that break-even point means for that business owner. The book example is about nachos, so choose something else that interests you.
