Use the following to answer the questions below:

Fast food restaurants are been required to publish nutrition information about the foods they serve. Nutrition information about a random sample of McDonald's lunch/dinner menu items (excluding sides and drinks) was obtained from their website. We wish to use the sodium content (in milligrams) to better understand the number of calories in the lunch/dinner menu items at McDonald's. Some summary statistics, partial computer output from a regression analysis, and a scatterplot (with regression line) of the data are provided.

Use two decimal places when reporting the results from any calculations, unless otherwise specified.

 Variable Mean StDev Calories 477.3 164.6 Sodium (mg) 1021.3 373.8
The regression equation is Calories = 99.69 + 0.3698 Sodium (mg)

 Source DF SS MS F P Regression 1 267501 267501 31.11 0.000 Error 13 111793 8599 ​ ​ Total 14 379293 ​ ​ ​

Use the equation of the least squares line to predict the number of calories in a lunch/dinner menu item with 1,000 mg of sodium.

▸ 448.38 calories.

▸ 505.63 calories.

▸ 424.89 calories.

▸ 469.49 calories.
