Buried change Drilling down beneath a lake in Alaska yields chemical evidence of past changes in climate. Biological silicon, left by the skeletons of single-celled creatures called diatoms, is a measure of the abundance of life in the lake. A variable based on the ratio of certain isotopes gives an indirect measure of moisture, mostly from snow. As we drill down, we look further into the past. Here is a scatterplot of data from 2300 to 12,000 years ago. Describe the effect the point in the upper-right corner has on the equation of the least-squares regression line.

9. pg 142 Buried change Drilling down beneath a lake in Alaska yields chemical evidence of past changes in climate. Biological silicon, left by the skeletons of single-celled creatures called diatoms, is a measure of the abundance of life in the lake. A variable based on the ratio of certain isotopes gives an indirect measure of moisture, mostly from snow. As we drill down, we look further into the past. Here is a scatterplot of data from 2300 to 12,000 years ago. Describe the effect the point in the upper-right corner has on the equation of the least-squares regression line. Silicon 350 300 250 200 150 100 50 0 -21.8 -21.4 -21.0 -20.6 -20.2 -19.8 -19.4 Isotope
