You will use this data for questions 5 - 7, so you might want to write this information on a separate sheet of paper. A data set is skewed right with a mean of 70 and a standard deviation of 10.

At least what percent of the data lies between 50 and 90?

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

10-9=1

1/8 - 1/9=

find l c d and then combine:
