The question as text
A five-sided spinner has edges marked 1, 2, 3, 4, 5. Ayesha believes that the spinner is biased so that it lands on five more often than it should. She spins the spinner 200 times, and it lands on five on 60 spins. Use Ayesha’s result to calculate an approximate 94% confidence interval for the probability that the spinner lands on five on one spin. [3]
