b. Assuming that a probability distribution is described, find its mean and standard deviation.

The mean is (Round to the nearest tenth as needed.)

The standard deviation is(Round to the nearest tenth as needed.)

c. Use the range rule of thumb to identify the range of values for usual numbers of bumper stickers.

The maximum usual value is(Round to the nearest tenth as needed.)

The minimum usual value is(Round to the nearest tenth as needed.)
