In 1918 and 1919 a worldwide outbreak of influenza killed more than 25 million people. Data on the number of new influenza cases and the number of deaths from the epidemic in San Francisco week by week from October 5, 1918, to January 25, 1919 is shown in the following table. The date given is the last day of the week. Date Cases 36 Deaths 0 Date Cases 722 Deaths 50 Oct. 5 Dec. 7 Oct. 12 Oct. 19 531 4233 0 130 Dec. 14 Dec. 21 1517 1828 71 137 Oct. 26 8682 552 Dec. 28 1539 178 Nov. 2 7164 738 Jan. 4 2416 194 Nov. 9 2229 414 Jan. 11 3148 290 Nov. 16 600 198 Jan. 18 3465 310 Nov. 23 164 90 Jan. 25 1440 149 Nov. 30 57 56 We expect the number of deaths to lag behind the number of new cases because the disease takes some time to kill its victims. Please make three scatterplots of deaths (the response variable) against each of new cases the same week, new cases one week earlier, and new cases two weeks earlier. Find the numerical value of the sample correlation coefficient that goes with your third plot (deaths vs new cases two weeks earlier). Round your final answer to 4 decimal places.

We expect the number of deaths to lag behind the number of new cases because the disease takes some time
to kill its victims.
Please make three scatterplots of deaths (the response variable) against each of new cases the same week,
new cases one week earlier, and new cases two weeks earlier. Find the numerical value of the sample
correlation coefficient that goes with your third plot (deaths vs new cases two weeks earlier).
Round your final answer to 4 decimal places.
