Use the test scores below:

81, 70, 73, 89, 68, 79, 91, 59, 77, 73, 80, 75, 88, 65, 82, 94, 77, 67, 82

23. what is a histogram of the data that uses intervals of 10?

you would make the histogram and then you would have to make intervals of 10 and put all the numbers in the right places

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.

right
