A manufacturer of chocolate topping uses machines to dispense liquid ingredientsinto bottlesthat move along a filling line. The machine that dispensestoppingsis working properly when 8grams are dispensed.The standard deviation of the processis 0.15 gram. A sample of 50 bottlesis selected periodically and the filling line is stopped if there is evidence that the average amount dispensed is actually lessthan 8 grams. Suppose that the average amount dispensed in a particularsample of 50 bottlesis 7.983 grams.

At the 0.05 level of significance, using the critical value approach to hypothesistesting,isthere evidence that the average amount dispensed is less than 8 grams?
