A machine used to fill beverage cans is supposed to put exactly 12 ounces of beverage in can to can. In a sample of 50 cans, the standard deviation of the amount was s=0.09 ounce. A simple random sample of filled cans will have their volumes measured, and a 98% confidence interval for the mean fill volume will be constructed. Estimate the number of cans that must be sampled for the margin of error to be equal to 0.02 ounce. The sample size required for the desired margin of error is n- (Round your answer to next whole number.)

A machine used to fill beverage cans is supposed to put exactly 12 ounces of beverage in each can, but the actual amount varies randomly from
can to can. In a sample of 50 cans, the standard deviation of the amount was s=0.09 ounce. A simple random sample of filled cans will have
their volumes measured, and a 98% confidence interval for the mean fill volume will be constructed.
Estimate the number of cans that must be sampled for the margin of error to be equal to 0.02 ounce.
