A manufacturer of liquid detergent claims that the mean weight of liquid in containers sold is at least 50 ounces. It is known that the population distribution of weights is normal with a standard deviation of 1.1 ounces. In order to check the manufacturer’s claim, a random sample of 30 containers of detergent is examined. The claim will be questioned if the sample mean weight is less than 49.8 ounces. What is the probability that the claim will be questioned if, in fact, the population mean weight is 50 ounces?
