70
100
determine whether or not to
80
84
serve caffeinated coffee for
65
65
their patients in the waiting
rooms. At this point, they are
77
84
not concerned about the
60
74
visitors, only people who will be
treated at the hospital. As a
90
100
75
85
state-of-the-art medical facility,
they know that many similar
88
98
facilities do serve coffee and
70
95
they want to determine if there
is sufficient evidence to show
78
80
70
80
that caffeinated coffee
62

increases heart rate.

The hospital tested 31 hospital
75

patients who each recently had

drank coffee. You are asked to
62

organize and analyze this data,
and present your results with
an appropriate hypothesis test
of whether caffeine significantly
