Aconsumer 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 4 grams with 95% confidence. the standard deviation of these jars is usually 3 grams. estimate the minimum sample size required.
