Population of cities and driving times are related, as shown in the accompanying table, which shows the 1960 population N, in thousands, for several cities, together with the average time T, in minutes, spent by residents driving to work. City Los Angeles Pittsburgh Washington Population N Driving time T 16.8 6489 1804 12.6 1808 14.3 Hutchinson 38 6.1 Nashville 347 10.8 Tallahassee 48 7.3 An analysis of these data, along with data from 17 other cities in the United States and Canada, led to a power model of average driving time as a function of population. (a) Construct a power model of driving time in minutes as a function of population measured in thousands. (Round regression parameters to two decimal places.) T = 3,40 x N0.18 T= 1.26 x N1.45 T= 6.84 x N0.87 T= 2.47 x N1.53 T= 4.53 x N0.26 (b) Is average driving time in Pittsburgh more or less than would be expected from its population? (Use the model found in part (a).) more than expected o less than expected (c) If you wish to move to a smaller city to reduce your average driving time to work by 15%, how much smaller should the city be? (Use the model found in part (a). Round your answer to two decimal places.)

A marketing firm is doing research for an Internet-based company. It wants to appeal to the age group of people who spend the most money online. The company wants to know if there is a difference in the mean amount of money people spend per month on Internet purchases depending on their age bracket. The marketing firm looked at two age groups, 1818-2424 years and 2525-3030 years, and collected the data shown in the following table. Let Population 1 be the amount of money spent per month on Internet purchases by people in the 1818-2424 age bracket and Population 2 be the amount of money spent per month on Internet purchases by people in the 2525-3030 age bracket. Assume that the population variances are not the same.
