When investigating times required for the drive-through service, the following results (in seconds) were obtained. Determine the range, variance, and standard deviation for each of the two samples, then compare the two sets of the results.
Restaraunt A= 120, 123, 153, 128, 124, 118, 154, 110
Restaraunt B= 115, 126, 147, 156, 118, 110, 145, 137
