Task One
Mr. P is analyzing the growth of some plants he bought from the store after x weeks. He
collects the following data, formatted as (weeks since buying the plant, height).
(7.0, 7.0)
(13.0, 11.0)
(10.0, 8.5)
(2.0, 3.5)
(4.0, 5.5)
(4.0, 3.5)
(6.0, 5.5)
(8.0, 7.5)
(11.0, 9.5)
(7.0, 5.5)
(10.0, 7.5)
(12.0, 9.5)
a. What relationship is there between
weeks since buying and height?
b. Are there any major clusters in the
data? Any outliers?
c. Is the relationship linear or nonlinear?
d. Describe the line of best fit by filling in the missing values (slope and y-intercept)
y = x +
e. For which data point above does the trend line (line of best fit) underpredict the data the
most?
