Essica is a custodian at oracle arena. she waxes 20 \text{ m}^220 m 2 20, space, m, start superscript, 2, end superscript of the floor in \dfrac35 5 3 ? start fraction, 3, divided by, 5, end fraction of an hour. jessica waxes the floor at a constant rate.

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.

i think the answer is true
