Question

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?

Answer 1

so to find the medium you need to put the numbers in order from least to greatest so for the first one it would be like this 103, 111, 113, 114, 122, 129,
130, 138, 140, 141, 145 and then you find the number that is in the middle of the set so for sample one it would be 129

Answer 2

Sample 1 median is 129
Sample 2 median is 117
