Some college students collected data on the intensity of light at various depths in a lake. Here are their data: Depth (meters) Light intenisty (lumens) 5 168.00 6 120.42 7 86.31 8 61.87 9 44.34 10 31.78 11 22.78 Take the natural logarithm (ln) of the light intensity measurements and calculate the least-squares regession equation for the transformed data to perform the inverse transformation to express light intensity as an exponential function of depth in the lake.
