8-21.

Inspect each data set below and the statement made about it. Each statement is false. *Without making any calculations*, determine how you can explain or justify that the statement is false. Homework Help ✎“The set of 24, 25 26, and 28 has a mean of 30.”

“15 is the median of this data set: 12, 14, 15, 13, and 16.”

Do you think the mean can be greater than all pieces of data?

Remember that the mean of a data set is the average number, but try not to make any calculations!

Be sure to check that the number set is in numerical order (from least to greatest)!
