Dont understand this: The following are the ages (years) of 5 people in a room:
13, 18, 14, 17, 24
A person enters the room.
The mean age of the 6 people is now 21.
What is the age of the person who entered the room?

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.

answer: -0.5 would be the most likley outcome
