Describe an overall pattern of the data. Is there a correlation between SmokeED and FruitVeg5? What does that tell you? r = -0.39 hence the plot shows a weak negative correlation between SmokeED and FruitVeg5. This tells us that an increase in SmokeED leads to a decrease in FruitVeg5 or vice versa. 020217

Pick a state in this data set and use its position in the graph in question 5 to write an interpretation of what it represents and how it compares with the other states. We can use the regression line equation to predict the value of FruitVeg5 by using SmokeEd. An example is Indiana where SmokeED = 19.4 FruitVeg5 = -0.447x + 30.12 = -0.447 (19.4) + 30.12 = 21.4482 8. Can you conclude that smoking everyday will cause you to or not to eat5 servings of fruits and vegetables per day? Explain your answer. No. The coefficient of determination (R 2 = 0.151) means that 1.51 of the variance in dependent variable (FruitVeg5) is predictable from the independent variable (SmokeED) 9. Using Excel, make a scatterplot to compare the data in Female (x-axis) and FruitVeg5 (y- axis) columns.Make sure you include the linear regression line on this graph.

What can you say about the association, if any, between gender and eating fruits and vegetables at least 5 servings a day? There is no association between gender and eating fruits and vegetables at least 5 servings a day since r = 0.01 020217

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
