The following data represent the miles per gallon for a particular make and model car for six randomly selected vehicles. Compute the mean, median, and mode miles per gallon.
24.1, 22.7, 37.8, 39.3, 39.1, 36.2
Compute the mean miles per gallon. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
A.The mean mileage per gallon is
nothing.
(Round to two decimal places as needed.)
B.
The mean does not exist.
Arranging in ascending order :
22.7 , 24.1, 36.2 , 37.8 , 39.1 , 39.3
Mean = Xi/n = (22.7+24.1+36.2+37.8+39.1+39.3)/6 = 199.2/6 = 33.2
Mode= 39.3(highest value)
Median = ((n/2)th + (n/2 +1)th)observation/2
=(3rd +4th )obs/2= (36.2+37.8)/2 = 74/2 = 37
