Jonathan's scout troop tie-dyed sweatshirts and T-shirts last year for a fundraiser. For every 20 sweatshirts, they dyed 30 T-shirts. This year, Jonathan's scout troop will keep the same ratio of sweatshirts to T-shirts. They plan to tie-dye 60 sweatshirts. How many T-shirts will Jonathan's scout troop dye this year?

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.

the answer is d on edge
