A consumer advocate wants to collect a sample of jelly jars and measure the actual weight of the product in the container. He needs to collect enough data to construct a confidence interval with a margin of error of no more than 2 grams with 99% confidence. The standard deviation of these jars is usually 2 grams. Estimate the minimum sample size required.
The minimum sample size required is ____ jars. (Round up to the nearest whole number.)
minimum sample size required is given by n=(z*Sd /E) 2 Where Sd =standard... View the full answer
