A fоrest mаnаgement teаm chооses a random sample of silver maple trees and measures their diameters (in inches) and records the age of each tree in years. The information is summarized in the following table. Diameter (x) in inches Age (y) in years 3.9 11.7 11.4 35.3 5.3 14.8 7.6 18.0 6.6 19.8 8.6 23.9 4.4 14.3 3.2 11.8 6.5 19.5 1. Find the linear correlation coefficient r for this data set. Round to three decimal places. [r] 2. A hypothesis test is to be done to determine if there is linear correlation between these two variables. The null and alternative hypotheses are given below. Use a 0.05 level of significance.
