Question

Martina chose a random sample of 10 bags of candy from two different Brands, A and B. All bags in the sample are the same size. Martina counts the number of candy pieces in each bag and plots the results on two dot plots.  Based on the plots, which statement is a valid comparison of the number of candies in the bags of the two Brands?
A. The number of candies in the bags from Brand B is greater and more consistent than the number of candies in the bags from Brand A.

B. The number of candies in the bags from Brand B is greater and less consistent than the number of candies in the bags from Brand A.

C. The number of candies in the bags from Brand B is fewer and more consistent than the number of candies in the bags from Brand A.

D. The number of candies in the bags from brand B is fewer and less consistent than the number of candies in the bags from brand A.

Answer 1

they are the same  by looking at the picture

Answer 2

Answer:

A. The number of candies in the bags from Brand B is greater and more consistent than the number of candies in the bags from Brand A.

Step-by-step explanation:

By looking the graph we see that number of candies from the bag of Brand B is greater than bag of Brand A as:

Number of candies in bag of Brand A= 52 + 52 + 53 + 55 +55 + 57+ 58 +58 +62 = 502 candies

Number of candies in bag of Brand B = 45 + 45 + 52 + 52 +55 + 62 +65 + 67 + 70 + 68 = 581 candies

And also we see that in bag of Brand B the spread in large in comparison of bag of Brand A.

Hence, option A is correct.
