The dataset starbucks in the open intro package contains nutritional information on 77 Starbucks food items. Spend some time reading the help file of this dataset. For this problem, you will explore the relationship between the calories and carbohydrate grams in these items. Please complete in R Studio showing all steps.

  • Create a scatterplot of this data with calories on the x-axis and carbohydrate grams on the y-axis, and describe the relationship you see.
  • In the scatterplot you made, what is the explanatory variable? What is the response variable? Why might you want to construct the problem in this way?
  • Fit a simple linear regression to this data, with carbohydrate grams as the dependent variable and the calories as the explanatory variable. Use the lm() function.

The file cereal.scsv contains the nutritional information for over 70 cereals. However it's in a format that is rarely used (semi-colon separated values). The reason it's in this format is that a few cereals have commas in their name (e.g. Fruit & Fibre Dates, Walnuts, and Oats). There is a separate lesson on converting this data to a proper csv format. Also note that the first line identifies the column names; the second line identifies the data types for each...
