An ecologist studying breeding habits of the common crossbill in different years finds that there
is a linear relationship between the number of breeding pairs of crossbills and the abundance of
the spruce cones. below are statistics on eight years of measurements, where x= average
number of cones per tree and y = number of breeding pairs of crossbills in a certain forest.
mean
23.0
18.0
standard deviation
16.2
mean number of cones/tree
y = number of crossbill pairs
105
the correlation between x and y is r=0.968
16. find the equation of the least-squares regression line (with y as the response variable).
