A machine used to regulate the amount of dye dispensed for mixing shades of paint can be set so that it discharges a desired average amount of dye per can of paint. The amount of dye discharged is known to have a normal distribution with a standard deviation equal to 0.5 milliliters (ml). If more than 15 ml of dye are discharged when making a particular shade of blue paint, the shade is unacceptable. Determine the setting for the mean so that no more than 1% of the cans of paint will be unacceptable.
