A company claims that the mean weight of coffee in its 16-ounce bags is 16.05 ounces. Consumer advocates group constructed the following 95% confidence interval (16.09, 16.12). Based on this interval, do you think that the company's claim is plausible at the 5% significance level? 16.05 lies in the interval (16.09, 16.12), so we do not reject the manufacturer's claim. 16.05 does not lie in the interval (16.0, 16.2), so we reject the manufacturer's claim. Not enough information to answer the question. 16.05 does not lie in the interval (16.09, 16.12), so we reject the company's claim.
