According to a recent economist report, an adult driver in America spends between $500 and $2500 on gasoline per year. Consider this spending pattern to be uniformly distributed.

1. What is the mean amount spent on gasoline?
2. What is the standard deviation of the amount spent?
3. What is the probability of a randomly selected adult spending less than $1000 on gasoline?
4. What is the probability of a randomly selected adult spending more than $2200 on gasoline?
