Which of the following explains the null and alternative hypotheses?
Null hypothesis: The long-run proportion of times that rhesus monkeys make the incorrect choice when the researcher
looks towards the correct box is 0.50 (just guessing).
Alt hypothesis: The long-run proportion of times that rhesus monkeys make the correct choice is less than 0.50.
$H_0: \pi = 0.5$, $H_a: \pi < 0.5$
