Alex puts his spare change in jar every night. If he has $11.09 at the end of January, $22.27 at the end of February, $44.35 in April, $75.82 in July, $89.00 in August, and $114.76 at the end of October, perform a linear regression on this data.
y = 11.34x - 0.897
correlation coefficient:: r = 0.9992

What does the value of the correlation coefficient tell you about the correlation of the data?
There is a very strong linear correlation between the month and the
amount of change in Alex's jar.
