- Urban Travel Times 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, sent by residents driving to work. City Population N Driving time T Los Angeles 6489 16.8 Pittsburgh 1804 12.6 Washington 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 b Is average driving time in Pittsburgh more or less than would be expected from its population? c If you wish to move to a smaller city to reduce your average driving time to work by 25, how much smaller should the city be?arrow_forwardIn a recent survey in the UK, it was found that about 85% of UK smokers are very much aware that smoking increases their risk of developing lung cancer, and 80% know the habit may lead to heart disease, The poll said that 75% of adult senokers surveyed believed smoking would probably shorten their lifespan. 85% said they had tried to stop smoking, averaging eight failed attempts to drop the habit. 40% of adult smokers smoke a packet or more a day. The poll questioned 1,000 UK residents by telephone between 11 and 15 January 2005, Answer the following questions about the survey: b)Write out clearly the general objective of the survey, Make a full list of the target variables in the study. c) Make a full list of the target variables in the study. d) State two advantages and two disadvantages of using telephone interviews in carrying out this particular survey, Construct close-ended questions to obtain information to compute the five estimates in the report.arrow_forward
