Probability of Observations


About one hundred samples of red wine of a single type have been analyzed for their alcohol content. Assuming that the given sample accurately represents the population of Italian red wines, try to answer the following questions:

What are the chances of finding a wine with more than 14 % alcohol?
Does this estimate change if you assume that the wines are normally distributed (if yes, how much?)

Use  DataLab  and the distribution calculator to answer the questions.
