Problem 2

A factory cans fresh pineapple in sugar syrup. The manager in charge is interested in estimating

the average amount of sugar per can to within 3 mg of the true mean. From previous

experiments, based on a very large sample, he knows that the standard deviation of the sugar

content is approximately 5 mg. Each test of measuring the amount of sugar in a can costs $ 19.

One thousand dollars have been budgeted for this experiment. Does the manager have enough

funds to estimate the average amount of sugar per can with a 92 percent confidence?
