C9. The Hate Crime Statistics Act of 1990 requires the attorney general to collect national data about crimes that manifest evidence of prejudice based on race, religion, sexual orientation, or ethnicity, including the crimes of murder and nonnegligent manslaughter, forcible rape, aggravated assault, simple assault, intimidation, arson, and destruction, damage, or vandalism of property. The Hate Crime Data collected in 2007 reveal, based on a randomly selected sample of 300 incidents, that the mean number of victims in a particular type of hate crime was 1.28, with a standard deviation of 0.82. Assuming that the number of victims was normally distributed, answer the following questions:

1. What proportion of crime incidents had more than two victims?

2. What is the probability that there was more than one victim in an incident?

3. What proportion of crime incidents had fewer than four victims?
