4. Researchers interested in canning counted the average number of surviving bacteria in a canned food product after different amounts of time (in minutes} of exposure to SUDC'F heat. A simple linear regression model for predicting average bacteria using the pledictor time was t, and then the following inverse response plot was created. Suggest the most appropriate transformation for bacteria base on the plot. At hactelia = 5U, the lines are ordered from the smallest {0.5} power at the top to the largest {1} at the bottom. c: 0 iii a '5 to c: N D 50 100 150 bacteria (a) No transformation {h} Inverse square root (c) Natural log {d} Square root
