b) r=
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. Complete parts a through c. Click the icon to view the data table. B. There is a strong, negative linear association. OC. There is a weak, positive linear association. OD. There is a strong, positive linear association. E. There is little or no association. (b) Find the correlation between the two variables in the scatterplot. What does the size of the correlation suggest about the strength of the association between these variables? r=
