16.) (show Work) The eruption height and the time interval after eruption of a geyser were measured and are shown below.
Height 120, 135, 130, 160, 140, 130, 150, 135
Interval after 75, 82, 104, 97, 60, 104, 102, 111
(a) Find the value of the linear correlation coefficient r
(b) Find the critical values of r form the table drawing the critical values for the Pearson correlation coefficient using a=0.05. the critical values are
(c) Is there sufficient evidence to conclude that there is a linear correlation between the two variables
