[R] I am using the Theoph data frame and I need help with the following problem in R:

Question 4) Determine the relationship between subject weight (Wt) and dose (Dose) Create a table in R that captures the following details [30 pointsl Note the 'Weight ranges', you will compute the mean dosage over the given weight intervals Weight range 55 and-65 >65 and 75 >75 Mean of dose By looking at the table can you draw any conclusion upon the relationship between subject weight and dose?
