Collect, organize, and analyze data.
Make predictions based on data.
According to the U.S. Food and Drug Administration, 30% of daily calories should come from fats and only 10% from saturated fats. Based on a 2,000-calorie-a-day intake, this translates to about 600 calories from fat and 20 grams of saturated fat.
By knowing the number of fat calories in a fast food item, can you predict the number of grams of saturated fat?
Your task:
I. 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 . Organize your data in a table.
II. Make a scatter plot of the data on graph paper. Be sure to label the axes and use an appropriate title for the graph.
You may wish to use a graphing calculator, spread sheet, or other technology resource to aid you in graphing.
Create a Graph
III. Draw a trend line for the scatter plot. Use the following scatter plot of the ordered pairs as an example.
IV. Calculate the slope of the trend line.
