The euphotic zone is the upper 200 m layer of the oceans. Very little sunlight penetrates deeper than 200 m, so most plants live in the euphotic zone. As a result, 70% of all photosynthesis on Earth occurs in the euphotic zone of the oceans. The following table gives light penetration data for the location in the Pacific Ocean. Depth (m) Penetration of Sunlight (%) 0.01 100 20 54.37 40 29.57 60 16.08 80 8.74 100 4.76

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 3/19 5/30 7/3 9/13 1/25 41.6 72.7 72.4 65.9 49.3 72.1 11/7 64.2 68.6 76.6 69.4 69.8 70.5 Date Initial Depth, X₁ Depth Five Years Later, Y; B. Using the same dates maximizes the difference in water clarity. C. Those are the same dates that all biologists use to take water clarity samples. D. Using the same dates makes the second sample dependent on the first and reduces variability in water clarity attributable to date. b) Does the evidence suggest that the clarity of the lake is improving at the α = 0.05 level of significance? Note that the normal probability plot and boxplot…
