A Question 13-
Retake question
A scatterplot will provide a suitable graphical display with which to view the nature
of the relationship between corn yield and land value. (HINT: It might help if
you sketch one for the data given in order to answer this question.) Which
observation (i.e., point in the scatterplot) is a suspected outlier?

A Question 14
Retake question
V Saved
Use the following information and scatterplot to answer the next question. Wild
bears in a sample of size m = 143 were anesthetized, and their bodies were measured
and weighed. One goal of the study was to make tables for hunters, so they could
estimate the weight of a bear based on other measurements. This scatterplot shows
the fitted least-squares regression line that models the linear association between
weight (Ibs.) and neck girth (in.). Notice that the equation of least-squares regression
that models the data is given with the graph. Which is the proper interpretation of
the slope in that equation?
