a)
The simple linear regression equation that shows the best relationship between the number of patients and year is (round your responses to three decimal places):
Ý=_____+_____x
where
Ý= Dependent Variable and x = Independent Variable.
b)
Using linear
regression,
the number of patients Dr. Fok will see in year
11=______ patients (round your response to two decimal places).
c)
Using linear regression, the number of patients Dr. Fok will see in year
12=______patients (round your response to two decimal places).
