A gas station owner would like to estimate the mean number of gallons of gasoline sold to his customers. Assume the number of gallons sold follows the normal distribution with a population standard deviation of 2 gallons. From his records, he selects a random sample of 58 sales and finds the mean number of gallons sold is 8.69. (Round your answers to 2 decimal places.) (a) The point estimate of the population mean is (b) The 99 percent confidence interval for the population mean is between and. .
