Would you use mean, median, mode, or range for each situation? explain. 8) jack noticed that half of the cereal brands in the store cost more than $2.00. 9) the average score on the last pre-algebra test was 77 . 10) the most common height on the basketball team is 6 ft 1 in. 11) the heights of players on the basketball team vary by 8 inches. 12) the most common price of a certain type of car is $25,000. 13) prices for tickets to the football game vary by $5. 14) one-half of the cars at a dealership cost less than $23,000.

The question isn't very clear, but I'll do my best to answer them anyways.
8) Median. Half of the cereal means the top or bottom half, so therefore $2.00 is the median.
9) Mean. Key word here is average.
10) Mode. "Most common" refers to the one that is expressed the most, thus mode.
11) Range. The problem talks about "varying", meaning the difference between the shortest and the tallest, and thus the range.
12) Mode. "Most common", similar to 10
13) Range. Key word here is varying, similar to 11
14) Median. "One-half" is the key word. See 8.

Here are the answers to the ones that i could see.
