20. Starbucks, calories, and carbs. The scatterplot below shows the relationship between the number of calories and amount of carbohydrates (in grams) Starbucks food menu items contain. Since Starbucks only lists the number of calories on the display items, we might be interested in predicting the amount of carbs a menu item has based on its calorie content. 17 Carbs (grams) 80 60 40 20 100 200 300 400 500 Calories Residuals 20 0 -20 20 30 40 50 60 Predicted carbs (grams) a. Describe the relationship between number of calories and amount of carbohydrates (in grams) that Starbucks food menu items contain. b. In this scenario, what are the predictor and outcome variables? c. Why might we want to fit a regression line to these data? d. What does the residuals vs. predicted plot tell us about the variability in prediction errors based on this model for items with lower vs. higher predicted carbs?

A chemical technician is filling one of 3 tanks of various sizes with a chemical. Write a program that will prompt a user to type in the number of gallons that are being put into a tank AND prompt the user to enter the tank number(1, 2, or 3) that they are putting the chemical into. Using a switch statement, determine the number of gallons that can be placed into this tank once the technician is done filling the tank in question. Print to the console screen, the number of gallons that be placed into the tank, include the tank number in the output statement. The output should look something like this: "Tank #2 can take 2000 gallons before it is full." The user fails to enter a valid tank number, the program should print to the screen: "Invalid tank number. Please try the program again" Use the table below to determine the capacity of each of the three tanks: Tank number 1 2 3 Capacity(in gallons) 5000 12000 8000 Test your program with the following data: 6000 gallons into tank 2 2000 gallons into tank 1 4000 gallons into tank 4
