1. Each year, the US Energy Department publishes an Annual Energy Review that includes the per capita consumption for each of the 50 states. If the mean of these 50 values is calculated, what is the result? Is the answer the mean per capita energy consumption for the population in all 50 states combined???

2. A set of data is at the nominal level of measurement and you want to obtain a representative data value. Mode is the most appropriate. Is this true?

3. The ABC Insurance company issues one-year policies to 12 men who are all 27 years of age. Each of these men has a 99.82 % chance of living through the year. The probability that they all survive the year is what?
