Aone-dollar bill is 0.0043 inch thick. if you had a billion one-dollar bills and made a stack of them, how high in miles would the stack be? remember that there are 12 inches in a foot and 5280 feet in a mile. (round your answer to two decimal places.)

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
