An insurance company selected a random sample of 500 clients under 18 years of age and found that 180 of them had had an accident in the previous year. A random sample of 600 clients aged 18 and older was also selected and 150 of them had had an accident in the past year. We want to conduct a hypothesis test to determine if the accident proportions differ between the two age groups.
a. What is the pooled proportion?
b. The p-value for this test is...
c. If we want to create a 95% confidence interval for the difference in accident rates between younger and older drivers, what is the LOWER bound of the interval? Round to 4 decimal places.
d. If we want to create a 95% confidence interval for the difference in accident rates between younger and older drivers, what is the UPPER bound of the interval? Round to 4 decimal places.
