Confidence Interval Problem Question 3 The inspection division of the LCC company wants to estimate the actual amount of soft drink in 2-liter bottles at the local bottling plant of a large nationally known soft-drink company. The bottling plant has informed the inspection division that the population standard deviation for 2-liter bottles is 0.05 liter. A random sample of 80 2-liter bottles at this bottling plant indicates a sample mean of 1.985 liter a) Construct a 99% confidence interval estimate...

1.Suppose we are estimating m. What happens to the required sample size as the desired margin of error increases while the population standard deviation and confidence level remain constant? 2. A quality control engineer would like to estimate the mean fill amount of a certain bottle-filling machine to within 0.05 liter. If we assume that the population standard deviation is 0.17 liters, how large of a sample is needed to estimate m with 98% confidence? 3.Assume the fill amount of...
