71.3

Step-by-step explanation:

Data set:

60, 60, 60, 60, 65, 65, 65, 65, 65, 65, 65, 70, 70, 70, 70, 70, 70, 70, 75, 75, 80, 85, 85, 90, 90, 90

Mean = total sum of numbers / amount of numbers

71.3

Step-by-step explanation:

add every score and divide by number of total students for the mean

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.
