A researcher studies water clarity at the same location in a lake on the same dates during the course of a year and repeats the measurements on the same dates 5 years later. The researcher immerses a weighted disk painted black and white and measures the depth (in inches) at which it is no longer visible. The collected data is given in the table below. Complete parts (a) through (c) below. Observation 1 2 3 4 5 6 Date 1/25 3/19 5/30 713 9/13 11/7 Initial Depth, X; 35 5 36.3 38.4 72.5 389 59.8 Depth Five Years Later, Yi 40 8 330 420 69 1 40.6 56.3
