Wayne Merritt drives from Cleveland to Chicago frequently and has noticed that traffic and weathec make a big diference in the timn it takes to mike the thp. Aa t result, he has a hard time planning activities around his arrival time. To better plian his business, Wayne wants to calculate his averago driving time as weil as a measure of how much an actual trip is likely to vary from that average. To do that, he clocked 10 trips w th the resuits in tables a. Calculate the mean, standard devation, and coelficient of varation of Waynef driving time to Chicago. (Hint: Treat tho 10 triss es the 10 possiole outcomes of a discrete probability distribution, each of which has a probability of 0.1.) Do nit rounid intermediate colculatiora. Round the answers to two dechal slaces. b. Calculate the average variation in driving time. Round the answer to two decimal places. (Hine the average veration is calculsted using the formula NX1X ) X ) minutes The average vatiaton is significantly lower than the standard deviabon. An average deviation would probably be V mearingful to Woyne
