The manager of a paint supply store wants to estimate the actual a mount of paint contained in 5-litre cans purchased from a nationally known manufacturer. It is known from the manufacturer’s specifications that the population standard deviation of the amount of paint is equal to 0.11 litres. A random sample of 50 cans is selected, and the sample mean amount of paint per 5-litre can is 4.98 litres.Calculate a 90% confidence interval estimate of the population mean amount of paint included in a 5-litre can. Round your answer to two decimal places with the lower bound first and the upper bound last.We are 90% confident that the true population mean amount of paint included in a 5-litre can is between_______ and ______ litres.If the manager of the same paint supply store wants to estimate the mean amount of paint in a 5-litre can to be within 0.05 litres with 95% confidence, what sample size is needed?
