Weston used the steps below to determine the percent equivalent to 1/40

in step 2, the second fraction should have been out of a multiple of 40.

in step 2, the multiplication relationship shown should have been division.

in step 4, the decimal should not have been moved.

in step 4, the decimal should have been moved two places instead of one.

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.
