A college student visits a large number of randomly selected stores in a city and in nearby small towns to collect data about the cost of bread. His theory is that the cost of bread is more variable in the city than in the small towns.

In the city, the sample MAD was 0.65, while in the small towns the sample MAD was 0.63.

Assuming there are no outliers or skew, do the results support the student's theory?

Select from the drop-down menus to correctly complete the statements.

Since the samples were large and randomly chosen, we can use the samples to understand the populations.

Because the sample MAD in the city is

the sample MAD in the small towns, the results

support the student's theory.

Step-by-step explanation:

i believe the answer is about the same and  do not tend to

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
