Question

a scuba diver used her camera equipment to measure the intensity of light, in lux, as she dove into the lake. She compared her readings with the depth of water at each point.

light intensity(lux) - 5.0, 4.0, 3.0, 2.0, 1.0

depth of water(m) - 2.3, 3.1, 4.0, 5.4, 7.7

(a) use logarithmic regression to model data, round all values to the nearest hundredth

(b) At what depth, to the nearest tenth of a metre is the light intensity 3.6 lux

(c) What is the light intensity at the surface, round to the nearest tenth
