Belinda has two freezers. Freezer A keeps frozen foods at a temperature of -20°F , while Freezer B keeps frozen foods at a temperature of -4°F. she transferred a package of frozen food from one freezer to the other. questions are What temperature difference between the two freezers? and another question If the temperature of the package rises after the transfer, from which freezer was the package ?

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.
