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
