Here is the probability model if we ignore the few households that own more than 5 cars: \begin{tabular}{|l|c|c|c|c|c|c|} \hline Number of cars X: & 0 & 1 & 2 & 3 & 4 & 5 \\ \hline Probability: & 0.09 & 0.36 & 0.35 & 0.13 & 0.05 & 0.02 \\ \hline \end{tabular}
27. What's the expected number of cars in a randomly selected American household? a. 1.00 b. 1.75 c. 1.84 d. 2.00 e. 2.50
28. The standard deviation of $X$ is $\sigma_{Y}=1.08$. If many households were selected at random, which of the following would be the best interpretation of the value 1.08 ? a. The mean number of cars would be about 1.08 . Sign out Nov 13 4:50 us
