Mr. Norman conducted a survey for the seventh grade at Hardin Park. There are 96 kids in the whole grade. He asked 10 random students in the hallway whether or not they would prefer lockers in the 7th grade or not. 6 said yes. About how many students out of the whole seventh grade would prefer lockers?
about 58

Charlie is finding the Mean Absolute Deviation of a data set. She notices that the MAD is very close to 0. What does this say about the data?
The data is very consistent and close together.

Claire is randomly choosing a cone for her ice cream. There are 7 waffle cones, 6 sugar cones, 16 cake cones, 4 chocolate cones, and 3 sprinkle cones. Write two statements comparing the probabilities of the cones to each other.
Example:
a sugar cone is 6/7 as likely to be chosen as a waffle cone.
