Question
A politician running for Senate in California claims that only 34% of Californians approve of the job
her competitor is doing. Melissa wants to test if this is true. She surveys 50 Californians.
1. Assuming the politician's claim about her competitor's approval rating is true, what is the
probability that more than 40% of those surveyed approve of the competitor?
2. If Melissa does find that more than 40% of those surveyed approve of the competitor, would
you doubt the politician's claim? Why or why not? (Consider this question on your own. You do
not have to provide an answer here.)
