Question

the parallel dotplots below display the number of cars parked for several days in each of two parking lots. 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.

Explanation:

Step1: Recall range formula

Range = Maximum - Minimum

Step2: Find range for lot A

For lot A, maximum = 29, minimum = 21, range = 29 - 21=8

Step3: Find range for lot B

For lot B, maximum = 29, minimum = 21, range = 29 - 21 = 8

Step4: Analyze standard - deviation concept

Standard deviation measures the spread of data. Data in lot B is more spread out than in lot A as values in lot B are more dispersed across different number - of - cars values. So, standard deviation of lot B is larger than that of lot A.

Answer:

None of the given statements are true.
