An automatic filling machine is used to fill $1-$liter bottles of cola. The machine$$s output is approximately normal with a mean of $0\mathrm{.}93$ liter and a standard deviation of $0\mathrm{.}01$ liter. Output is monitored using means of samples of $27$ observations. Use Table$-$A$.$

a$.$Determine upper and lower control limits that will include roughly $97$ percent of the sample means when the process is in control. $($Do not round intermediate calculations. Round z value to $2$ decimal places. Round your answers to $4$ decimal places.$)$
