Based on data from a car bumper sticker study, when a car is randomly selected, the number of bumper stickers and the corresponding probabilities are as shown below. complete parts (a) through (d)

Does the given information describe a probability distribution?

Yes

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

The mean is equal to 0.6. The standard deviation is equal to 1.5

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

The maximum usual value is 3.5.

max: μ + 2σ = 0.578 + 2(1.462161414) = 3.502322828

The minimum usual value is 0.

min: μ – 2σ = 0.578 – 2(1.462161414) = -2.346322828

Is it unusual for a car to have more than one bumper sticker? Explain.

No, because the probability of having more than one bumper sticker is equal to 0.120 that is greater that 0.05

The answer would be 24mm

The slope of the function is 0.5.
