1. Create a scatterplot in which the explanatory variable is the age, and the response variable is the race time. You must have all of your R code saved in a script called:age_times.R For your convenience, here is the vector to create one of the variables. You can paste it

into your R script:

age <- c(17.5, 15.6, 16.3, 18, 18, 17.1, 17.1, 14.9, 16.7)

Generate the other vector using the table above. When you are done, your graph should look something like this:
