An insurance company selected samples of clients under 18 years of age and over 18 and recorded the number of accidents they had in the previous year. The results are shown below. Under Age of 18 Over Age of 18 n1 = 500 n2 = 600 Number of accidents = 180 Number of accidents = 150
We are interested in determining if the accident proportions differ between the two age groups. The p-value is:

Question 2 (2 points) Random samples from two age groups of brides (200 brides under 18 years old and 100 brides showed that 50% of brides in the under 18 group were divorced after 15 years, while 40% of brides n the 20 or older group were divorced after 15 years. The difference between the two proportions is 0.10 with a standard error of 0 is a 95% confidence interval for the difference between the population proportions of brides who...
