A pet store paid $400 for the license to sell Fun Size stuffed animal dog toys. In addition, each stuffed animal dog toy costs the store $3. The store sells each toy for $7. In order to not lose money on the Fun Size stuffed animai dog toys, what is the minimum number of these stuffed animal dog toys the store must sell?​

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.
