Apply the binomial test to the example in the guide with probability of success 0.2. First use 5 pen per 10 successes out of 20 counts, then change to 8 successes out of 20.

Apply the proportion test and chi-square test to the example in the guide, which assumes we obtain 10, 12, 13 grass pixels (hits) out of 80, 90, 85 examined for each area.
