According to empirical property of distributions,
99% values lie between (mean - 3*sd, mean + 3*sd)
Here,
mean - 3*standard deviation = 13.77 - (3*0.12) = 13.41
mean + 3*standard deviation = 13.77 + (3*0.12) = 14.13
Since 14.17 lies outside the interval (13.41, 14.13), so we can say it is unusual for a can to contain 14.17 oz of soda.
a) Minimum usual value = 13.41
b) Maximum usual value = 14.13
c) Yes, because it is larger than the maximum "usual" value.

Workers at a certain soda drink factory collected data on the volumes (in ounces) of a simple random sample of 22 cans of the soda drink. Those volumes have a mean 12.19 oz and a standard deviation of 0.12 oz, and they appear to be from a normally distributed population. If the workers want the filling process to work so that almost cans have volumes between 11.89 oz and 12.57 oz, the range rule of thumb can be used to...
