Suppose a wholesaler of paints wants to estimate the actual amount of paint contained in 1.0 - kg cans purchased from a paint manufacturing company. It is known from the manufacturer's specifications that the standard deviation of the amount of paint is equal to 0.02 kg. A random sample of 50 cans is selected and the average amount of paint per 1.0 kg can is 0.995 kg.Do you think that the wholesaler has a right to complain to the manufacturer at a level of significance of 1%? Why?

Step 1
In this case: - H0: The average amount of paint in the cans is 1.0 kg (µ = 1.0 kg). - H1: The average amount of paint in the cans is not 1.0 kg (µ ≠1.0 kg). Show more…

A large paint retailer has had numerous complaints from their customers regarding underfilled paint cans. As a result, the retailer has begun inspecting incoming shipments of paint from suppliers. Shipments with underfill problems will be returned to the supplier. A recent shipment contained 2,440 cans. The retailer sampled 50 cans and weighed each on a scale capable of measuring weight to four decimal places. Properly filled cans need to weigh 10 kilogram; the average of the measured cans is 9,5 kilograms and the standard deviation is 0,3 kilograms. As the Quality Director of the company, describe the population, the variable of interest, the sample and the inference. If you are insisting that the process is filling the cans as planned, how much risk are you willing to take?

The manager of a paint supply store wants to estimate the amount of paint contained in 1-gallon cans purchased from a nationally known manufacturer. The manufacturer's specifications state that the standard deviation of the amount of paint is equal to 0.02 gallon. A random sample of 50 cans is selected, and the sample mean amount of paint per 1-gallon can is 0.995 gallon. (a) Construct a 99% confidence interval estimate for the population mean amount of paint included in a 1-gallon can. (b) Based on these results, do you think that the manager has a right to complain to the manufacturer? Why? (c) Must you assume that the population amount of paint per can is normally distributed here? Explain. (d) Construct a 95% confidence interval estimate. How does this change your answer to (b)?
