Answer to Question #82026 in General Chemistry for patrick phiri

Question

An ecologist wanted to establish the strength and nature of relationship that exists between light and the rate of photosynthesis for a particular tree species. She obtained paired values of light interception (in mol m-2s-1) and photosynthetic rate (in mol m-2s-1) on the leaves of the tree species. The results of the experiment are shown in the table below.

Amount of
Light
Intercepted 0.76 0.77 0.80 0.83 0.84 0.84 0.86 0.92 0.99 1.00 1.01
Rate of
Photosynthesis 7.6 9.5 10.8 11.5 11.7 12.7 12.6 13.3 13.9 14.0 14.0

a) Calculate the correlation coefficient for the data and interpret.
b) Estimate the regression line for the data. ]
c) Using the estimated regression line, estimate the amount of light intercepted when the rate of photosynthesis is 10.0.
