13. A machine used to regulate the amount of dye dispensed for mixing shades of paint can be
set so that it discharges an average of u milliliters of dye per can of paint. The amount of dye
discharged is known to have a normal distribution with a variance equal to 0.0160. If more
than 6 milliliters of dye are discharged when making a particular shade of blue paint, the shade
is unacceptable. Determine the setting of u so that no more than 1% of the cans of paint will
nombe unacceptable.
