A brand of water-softener salt comes in bags marked “net weight 18kg”. The company that packages the salt claims that the bags contain an average of 18kg of salt and that the standard deviation of the weight of the bag is 0.68kg. Assume that the weight of the bags is normally distributed and unless otherwise indicated use ? = .05. It is given that: μ=18 0.68 n = 10 In general, what mean weights of 10 randomly select bags would you consider evidence against the company’s claim?
