A coffee manufacturer claims that the mean amount of coffee in its 3-ounce jars is 3.1 ounces. Based on a sample of 50 jars, a consumer advocate group obtains the following 98% confidence interval for the population mean weight, u: 2.95 ounces to 3.05 ounces. Based on this interval, do you think that the manufacturer's claim is plausible? Possible? Explain your thinking.

A coffee manufacturer claims that the mean amount of coffee in its 3-ounce jars is 3.1 ounces. Based on a sample of 50 jars, a consumer advocate group
obtains the following 98% confidence interval for the population mean weight, u: 2.95 ounces to 3.05 ounces. Based on this interval, do you think that the
manufacturer's claim is plausible? Possible? Explain your thinking.
We can be 98% confident that the true mean weight lies between 2.95 and 3.05
O ounces. Since this interval does not include the value 3.1, the manufacturer's claim is
unlikely to be true. Nevertheless, the manufacturer's claim is not impossible.
