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.
also, median= , because number of observations is even, so median is mean of two mid values.
now, coming to bandits
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.
