3) Adam rides his bike from his home to the school's bike lot at point F each day. Assuming he takes the same route home, how far does he bike to school and back each day? Each unit represents one block. A) -12 blocks B) 4 blocks C) 6 blocks D) 12 blocks

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.
