The parallel dotplots below display the number of cars parked for several days in each of two parking lots. 2 dotplots titled parked cars by lot. The number lines go from 21 to 29 and are labeled number of cars. For lot A, 21, 1; 23, 5; 25, 10; 27, 5; 29, 1. For lot B, A, 2; 23, 10; 25, 20; 27, 10; 29, 2.

Which of the following statements is true?

The range for the distribution of the number of cars is larger in lot A.
The range for the distribution of the number of cars is larger in lot B.
There is a smaller standard deviation in the distribution of the number of cars in lot B.
The standard deviation in the distribution of the number of cars is the same for both lots.

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.
