Forty trucks and suvs participated in a 30 mile race. the average driving speeds of the trucks and suvs were recorded. two random samples of 11 each were taken. a random sample (sample 1) of the trucks' average driving speed (km/h) is: 130, 122, 114, 129, 113, 103, 140, 111, 145, 138, 141. a random sample (sample 2) of the suvs' average driving speed (km/h) is: 112, 131, 114, 117, 129, 90, 122, 130, 113, 124, 105. what is the median of sample 1? what is the median of sample 2?
