Use the following sample data to answer the next questions. The table
represents results from an experiment with patients afflicted in both eyes with

eye was treated with eye drops. Using a .05 significance level, apply McNemar's

the laser treated eye and an improvement on the drops treated eye is the same as
the proportion of patients with an improvement on the laser treated eye and no
improvement on the drops treated eye.
