Amanufacturer of salad dressings uses machines to dispense liquid ingredients into bottles that move along a filling line.
the machine that dispenses dressing is working properly when 8 ounces are dispensed. the standard deviation of the process is 0.15 ounces.
a sample of 48 bottles is selected periodically, and the filling line is stopped if there is evidence that the mean amount dispensed is different from 8 ounces.

suppose that the mean amount dispensed in a particular sample of 48 bottles is 7.983 ounces.

calculate the p-value.
