Question

Which statement correctly compares the spreads of the distributions?

A. The range of penguin heights is greater at Countyside Zoo than at
Park Zoo

B. The range of penguin heights is greater at Park Zoo than at
Countyside Zoo.

C. The mode of penguin heights at Countyside Zoo is greater than the mode at Park Zoo

D. The ranges of penguin heights are the same.

Answer 1

A

Explanation:

Range = Highest value - Lowest value

At Park Zoo:

R = 44 - 38

= 6

At Countryside Zoo;

R = 45 - 38

= 7

So, it cannot be D, because the ranges are not the same and it cannot be B because the range is greater at countryside zoo

The mode is the value that appears the moat frequently.

At Park zoo, the mode is 41 since it has the most dots.

At Countryside zoo, the mode is 40, since it has the most dots

So, it cannot be C because Park zoo has a greater Mode.

so, the only answer is A
