1. Collect data from several fast food chains on the number of fat calories and grams of saturated fat in menu items. Record at least 12 ordered pairs of (fat calories, grams of saturated fat). Organize your data in a table.
2. Make a scatter plot of the data.
3. Draw a trend line for the scatter plot.
4. Calculate the slope of the trend line.
5. Using the slope and y-intercept, write the equation of the trend line.
6. Choose a "calories from fat" value that is not in your collected data set and that is at least 10 fat calories away from any collected value. Use the equation calculated in step 5 to predict the number of fat grams in an item having that number of fat calories. Be sure to show your work.
7. Search for an item in a fast food menu having the same number of fat calories as the one you chose in step 6. (If you cannot find the exact value, get as close as you can.) Compare the calculated value from step 6 to this actual value. Explain why (or why not) you would have expected your prediction (calculated value) to be close to the actual value.
