I need help with an assignment.

1) I have two apples, one banana, one cherry.Does it make sense to calculate the "average" of these things?Would you code that as a factor or a numeric value in R?

2) I have four quiz scores: 94, 93, 85, and 0.What is the mean (average) of my quiz scores? Would you code this as a factor or a numeric value in R?

3) In another class, I received these grades on my quizzes: two As, one B, and one F.What is the mean (average) of my grades? Would you code that as a factor or a numeric value in R? Think about how you would actually enter the values into R.

4)How would you explain the difference in mean values obtained in #2 and #3 above?

There is no requirement to use sources from the Internet, but if you use an idea or a quotation from any source, it should be cited (such as putting the author and year at the end of the sentence and then adding a reference at the end to describe the source).
