Orange trees ~ In the
1960s, a botanist was conducting a research on orange trees. He
wanted to figure out the relationship between the growth of trees
and their ages. The botanist gathered a random sample of 35 orange
trees and recorded the circumference of the tree in mm and the age
of the tree in days.
Circumference of tree is the X variable and Age of tree is the Y
variable in this scenario. Give all answers to four
decimals.
Variable |
Average |
Standard Deviation |
Circumference (X) |
114.5 |
56.5 |
Age (Y) |
921 |
490 |
The correlation coefficient between the variables X and Y is r = 0.89.
What is the estimated/predicted Age for the tree called Amber?
