An insurance company states that at least 87% of its claims are settled within 30 days. A consumer group selected a random sample of 69 of the company's claims to test this statement. They found that 57 of the claims were settled within 30 days. Does the consumer group have evidence to disbelieve the insurance company's claim?

1. Write the hypotheses to test if the rate of claims settled within 30 days is less than 87%.

Ho: The proportion of claims settled within 30 days is equal to 87%.

Ha: The proportion of claims settled within 30 days is less than 87%. 2.

To setup a simulation for this situation, we let each claim be represented with a card. We take 100 cards, 60.03 black cards represent claims that are settled within 30 days and 60.03 red cards represent claims that take longer than 30 days to settle. Shuffle the cards and draw with A and call it replacement blank cards representing the random sample of claims. Calculate the proportion of black & cards in the sample @sim Repeat 10,000 times and plot the resulting sample proportions. The p-value will be the proportion of simulations where @sim is greater than or equal to blank
