The shape of the distribution of the time required to get an oil change at a 10-minute oil change is unknown However, records indicate that the mean time is 11.6 minutes,and the standard deviation is 4.5 minutes. (c) Suppose the manager agrees to pay each employee a $50 bonus if they meet a certain goal. On a typical Saturday, the oil-change facility will perform 40 oil changes between 10 A.M. and 12 P.M. Treating this as a random sample, there would be a 10% chance of the mean oil-change time being at or below what value? This will be the goal established by the manager. There is a 10% chance of being at or below a mean oil-change time of nothing minutes. (Round to one decimal place as needed.)

The shape of the distribution of the time required to get an oil change at a
10-minute oil change is unknown However, records indicate that the mean time is 11.6 minutes,and the standard deviation is 4.5 minutes.
(c) Suppose the manager agrees to pay each employee a $50 bonus if they meet a certain goal. On a typical Saturday, the oil-change facility will perform 40 oil changes between 10 A.M. and 12 P.M. Treating this as a random sample, there would be a 10% chance of the mean oil-change time being at or below what value? This will be the goal established by the manager.
There is a 10% chance of being at or below a mean oil-change time of
nothing minutes.
(Round to one decimal place as needed.)
