Refer to the example in Section 8 .1 .2.

a. Using the model fit, calculate an odds ratio that describes the estimated effect of length on primary food choice being either "invertebrate" or "other."

b. Estimate the probability that food choice is "invertebrate," for an alligator of length 3.9 meters.

c. Find the length at which the outcomes "invertebrate" and "other" are equally likely.
