A limnologist takes samples from a creek on several days
and counts the numbers of flatworms in each sample,
The limnologist wants to look at the relationship between
the temperature of the creek and the number of
flatworms in the sample. The data show a linear pattern
with the summary statistics shown below:
mean
standard
deviation
= 10.2
Sx = 2.8
x = creek temperature
(C)
j = 37.6
$y = 30.8
y = number of
flatworms
• = -0.98
Find the equation of the least-squares regression line
for predicting the number of flatworms from the
creek temperature.
Round your entries to the nearest hundredth.
