For the data in #1, find the mean and standard deviation using a calculator. Write down the break points for ±1 ±2 and ±3 . Place the data in order and count the number of items in each of the classes. Then, find the percent of the data in each standard deviation class. Write them out on your sheet.

Using a calculator, find the standard deviation of the data set, including the new values. Which values are within 1 standard deviation of the mean? Are any data values more than 2 standard deviations from the mean? Add two more data values, one above and one below the mean, which will increase the standard deviation.
