A restaurant knows that the weights of its quarter-pound hamburgers (before cooking) are normally distributed with a mean µ pounds and standard deviation of 0.02 pounds. A manager wants to infer about the population mean weight µ. To this end, he randomly selected 64 hamburgers and found the sample mean weight was x̅ = 0.242 pounds. Find a 90% confidence interval for µ.
