Explanation / Answer

a) C. Yes, the population is normally distributed and the sample does not contain any outliers.

From the Q-Q plot, we can see that the points are more or less linear and close to the center line and no data point is far from the other data. So there are no outliers and the population is normally distributed. We can also see from the boxplot that there are no outliers. The distribution is bell-shaped and symmetric, which lead us to the answer C.
