Question 1- An insurance company collects data on seat-belt use among drivers in a country. Of 1800 drivers 20-29 years old, 35% said that they buckle up, whereas 479 of 1500 drivers 45-64 years old said that they did. Find a 90% confidence interval for the difference between the proportions of seat-belt users for drivers in the age groups 20-29 years and 45-64 years. The 90% confidence interval for p1-p2 is? Question 2- The coefficient of determination of a set...
