The accompanying computer excel output
(please see attachment on Blackboard) provides details of data and
analysis on the topic of “patient satisfaction”. A hospital
administrator wished to study the relation between patient
satisfaction (Y) and patients’ age (X1, in years) , severity of
illness (X2), and anxiety level (X3).
The output includes a listing of all
46 observations; descriptive statistics for each variable; and, the
results of a regression analysis that uses patient satisfaction as
the dependent variable, and patient’s...
