A researcher studies the relationship between the number of hours of sleep per night and the performance on a
memory test. Study participants are randomly selected to
get no sleep or sleep in 1-hour increments, up to 8 hours
total (that is, the participant gets 1 hour, 2 hours, and so
on, up to 8 hours of sleep). The researcher determines
that the association between the two variables can be
modeled with the linear equation p = 9h + 15, where h is
number of hours of sleep and p is the percentage score
on the memory test. Use the slope in the equation to
describe the association between the hours of sleep and
the performance on the memory test.
