A small cruising ship that can hold up to 52 people provides three-day excursions to groups of 34 or more. If the group contains 34 people, each person pays $58. The cost per person for all members of the party is reduced by $1 for each person in excess of 34. Find the size of the group that maximizes income for the owners of the ship.

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.
