Jonah is looking at some information for the obstacle course he is interested in completing. the x-coordinate is the number of the obstacle, while the y-coordinate is the average time to complete the obstacle, measured in minutes.
(1, 7.25), (2, 7.975), (3, 8.7725), (4, 9.64975)
jonah use an explicit formula to find the average time he will need for the 9th obstacle.
a. f(9) = 7.25(1.1)9; f(9) = 17.095
b. f(9) = 1.1(7.25)8; f(9) = 8396469
c. f(9) = 1.1(7.25)9; f(9) = 60874407
d. f(9) = 7.25(1.1)8; f(9) = 15.541

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.
