Final answer:
For parking next to a curb, you should park within 12 inches of the curb. In the De Anza parking garage example, on average, 8.25 out of 22 cars are parked crookedly. Option B is correct.
Step-by-step explanation:
When parking next to a curb, the correct position to park your vehicle is within 12 inches of the curb. This is to ensure that your vehicle does not obstruct traffic and follows local parking regulations. Typically, local or state traffic laws will determine the exact distance required, but, generally, within 12 inches is the standard guideline.
Regarding the probability calculation from the De Anza parking garage survey, to find how many cars, on average, are parked crookedly out of 22, you would multiply 22 by 37.5%, giving you 8.25 cars.
To calculate the probability of at least 10 of the 22 cars being parked crookedly, a binomial probability distribution or normal approximation could be used, depending on the level of precision required and the context of the question. However, since exact probability values have not been calculated in this scenario, we must refrain from incorrectly stating these values without proper computation.
