indicates that you should use R and provide the R code for the question.

1.* The height (in feet) and volume of usable lumber (in cubic feet) of 6 cherry trees are measured by a researcher.

X: Height (in feet)	61	65	75	80	85	90
Y : Volume of usable lumber (in cubic feet)	7	15	27	38	38	55

The data set can be read into R using the following code:

x <- c(61, 65, 75, 80, 85, 90)

y <- c(7, 15, 27, 38, 38, 55)
