23. a glass box shaped like a rectangular prism has width 7 inches, length 9 inches, and height 12 inches. it is being shipped in a larger box with width 10 inches, length 10 inches, and height 15 inches. the space between the glass box and the shipping box will be filled with styrofoam peanuts. how many cubic inches of space will contain styrofoam peanuts? show all work.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
