Question: (1 point)

A confectionery company normally produces bocks of chocolate that average 250 grams in size. Management have decided to reduce the average block size down to 200 grams. This requires new moulds and adjustments to the math me that squirts the chocolate into the moulds. The chocolate squirting machine does not have a dial controlling the amount squirted into each mould. Instead the mechanics need to use a trial and error process of adjusting the pressure of the chocolate and the timer for the valve. Experience has shown that the standard deviation of the amount of chocolate squirted each time is 8 grams. How many test blocks of chocolate need to be made after each adjustment if management want to be 99% sure that the mean amount of chocolate squirted into each block is accurate to within 4.5 grams.
