Please help me asap.

C is the correct answer.

Step-by-step explanation:

given: 12, 39, 21, 18, 24, 17, 12, 25

arrange them in increasing order:

12, 12, 17, 18, 21, 24, 25, 39

solve:

outlier refers to the unit which is minimum or maximum unit in the data.

Here outlier: 39

mean with the outlier:

(sum of units)/(total number) = (168)/(8) = 21

mean without outlier:

(sum of units-39)/(total number) = (168-39)/(7) = 18.4

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.

step-by-step explanation:

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.
