-Plot the scatterplot to show the relationship between height and weight, label the value for each participant.
-Base on the scatterplot, describe the relationship between height and weight (form, direction, strength, possible outlier)?
-Calculate the correlation coefficients. Does it confirm your judgment in the previous question?

A researcher is examining the relationship between height
(measured in centimeters) and weight (measured in kilograms). They
obtain a correlation coefficient of r = 0.3045. Suppose that the
researchers change their measurements to inches (1inch = 2.5400cm)
and pounds (1lb = 0.4536kg). After this change of units, what will
the new correlation coefficient be?

The data below represents height in inches/weight in pounds.
Clearly identify the dependent and independent variables as well as
the domain and range. Choose any two points from the data using
different independent variables and use those two points to
determine the rate of change (slope). Then, using the dependent
data value of -500 as your initial value, write an equation for the
linear function model. Predict what you expect at a height of
75".
