The annual per capita consumption of bottled water was 34.2 gallons. Assume that the per capita consumption of bottled water is approximately normally distributed with a mean of 34.2 and a standard deviation of 10 gallons.

1. What is the probability that someone consumed more than 34 gallons of bottled water? (Round to four decimal places as needed.)
2. What is the probability that someone consumed between 20 and 30 gallons of bottled water? (Round to four decimal places as needed.)
3. What is the probability that someone consumed less than 20 gallons of bottled water? (Round to four decimal places as needed.)
4. 97.5% of people consumed less than how many gallons of bottled water? (Round to two decimal places as needed.)
