Does the given information
describe a probability distribution?
</span>
Yes
<span>
Assuming that a probability
distribution is described, find its mean and standard deviation.
</span>
The mean is equal to 0.6. The standard deviation is equal to 1.5
<span>
Use the range rule of thumb to
identify the range of values for usual numbers of bumper stickers.
</span>
<span>The
maximum usual value is 3.5.</span>
<span>max: μ + 2σ = 0.578 + 2(1.462161414) =
3.502322828</span>
<span>The
minimum usual value is 0.</span>
<span>min: μ – 2σ = 0.578 – 2(1.462161414) =
-2.346322828</span>
<span>
Is it unusual for a car to have
more than one bumper sticker? Explain.
</span>
No, because the probability of
having more than one bumper sticker is equal to 0.120 that is greater that 0.05
