According to an automobile association, the average cost of a gallon of regular unleaded fuel at gas stations in a certain month was $2 827. Assume that the standard deviation of such costs is $0 15. Suppose that a random sample of n100 gas stations is selected from the population and the month's cost per gallion of regular unleaded fuel is determined for each Considor & the sample mean cost per gallon.

Workers at a certain soda drink factory collected data on the volumes (in ounces of a simple random sample of 22 cans of the soda drink. Those volumes have a mean of 12.19 oz and a standard deviation of 0.12 r. and they appear to be from a normally distributed population. If the workers want the filing process to work so that almost alcans have volumes between 12.01 oz and 12 53 oz, the range rule of thumb can be...
