The mean auto insurance rate for 22 drivers in a large city is $1,803 per car with a standard deviation of $364 while the mean rate for 30 drivers in a rural area is $1,621 with a standard deviation of $213. At = 0.05, can we conclude that drivers in the large city pay higher insurance rates than those in the rural area, assuming the population variances are equal?
