Math Problem Statement
Question content area top Part 1 In 2008, the per capita consumption of soft drinks in Country A was reported to be 19.24 gallons. Assume that the per capita consumption of soft drinks in Country A is approximately normally distributed, with a mean of 19.24 gallons and a standard deviation of 5 gallons. Complete parts (a) through (d) below. Question content area bottom Part 1 a. What is the probability that someone in Country A consumed more than 12 gallons of soft drinks in 2008? The probability is enter your response here. (Round to four decimal places as needed.) Part 2 b. What is the probability that someone in Country A consumed between 4 and 6 gallons of soft drinks in 2008? The probability is enter your response here. (Round to four decimal places as needed.) Part 3 c. What is the probability that someone in Country A consumed less than 6 gallons of soft drinks in 2008? The probability is enter your response here. (Round to four decimal places as needed.) Part 4 d. 97% of the people in Country A consumed less than how many gallons of soft drinks? The probability is 97% that someone in Country A consumed less than enter your response here gallons of soft drinks. (Round to two decimal places as needed.)
