The number of dry cleaning orders picked up at Sunny Fresh Dry Cleaners was sampled over 12 hour periods. Below is the sample:
142 171 125 91 140 125 97 125 162 142 125 117 89 125 140 128

From this data set, compute the sample mean, median, mode and midrange. Compute the 1st
quartile and 3rd and interpret their meanings.


I'm pretty sure i did this part correct, but im confused with the second part....

mean: 2044/127.75
median: 8 + 9 = 17/2 = 8.5
mode: 125
Range: 73??
