Each month, a government agency releases its latest
estimate of construction activity in the housing industry. A key
measure is the percentage change in the number of new homes under
construction. Does the release of this number come with a change in
the stock market? The accompanying data show the percentage
change in the number of new, privately owned housing units
started each month, as reported by the government agency. The
data also include the percentage change in the S&P 500
index on the same day the government agency releases the housing
results.
(b) Find the correlation between the two variables in the
scatterplot (attached below). What does the size of the correlation
suggest about the strength of the association between
these variables?
