Gets brainliest and 11 pts! the dot plots below show the distances traveled by two groups of skaters: two dot plots are labeled group x and group y. the horizontal axis is labeled distance traveled and marked from 15 to 40 at increments of 5 for both dot plots. group x shows 3 dots on 20, 7 dots on 25, 1 dot on 30, 2 dots on 35, 5 dots on 40. group y shows 3 dots on 15, 2 dots on 20, 6 dots on 25, 4 dots on 30, and 3 dots on 35. which of the following inferences can be made using the dot plots? group x has a higher mean than group y. group y has a higher mean than group x. there is no overlap between the data. the range of each group is different.

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.
