If Set Y is defined as the set of members that is greater than 5 but less than and equal to 9. which option best list out set Y members? {5, 6, 7, 8, 9}
{6, 7, 8}
{5, 6, 7, 8, 9, 10}
{6, 7, 8, 9}

b) 36

step-by-step explanation:

18 times 2 is 36

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.
