The mean of the commute time to work for a resident of a certain city is 27.3 minutes. Assume that the standard deviation of the commute time is 7.1 minutes to complete parts (a) through (c). (a) What minimum percentage of commuters in the city has a commute time within 2 standard deviations of the mean?
nothing% (Type an integer or a decimal.)
(b) What minimum percentage of commuters in the city has a commute time within 1.5 standard deviations of the mean? What are the commute times within 1.5 standard deviations of the mean?
The minimum percentage of commuters in the city that has a commute time within 1.5 standard deviations of the mean is nothing%. (Round to one decimal place as needed.)
The commute times within 1.5 standard deviations of the mean are between nothing and nothing.
(Type an integer or a decimal. Use ascending order.)
(c) What is the minimum percentage of commuters who have commute times between 6  minutes and 48.6 minutes?
nothing% (Round to one decimal place as needed.)

Acompany produces packets of soap powder labeled “giant size 32 ounces.” the actual weight of soap powder in such a box has a normal distribution with a mean of 33 oz and a standard deviation of 0.7 oz. to avoid having dissatisfied customers, the company says a box of soap is considered underweight if it weighs less than 32 oz. to avoid losing money, it labels the top 5% (the heaviest 5%) overweight. how heavy does a box have to be for it to be labeled overweight?
