A hardware retailer has average sales of $64,235 with a standard deviation of $5,918 for a 12-month period. The mean monthly sales for all retailers in the chain are $59,844. Is this hardware retailer's sales significantly different from all retailers in the chain at p= .05? Are they significantly different at p= .01? Calculate a .95 confidence interval for the data in problem.

Explain your findings and determine what question the confidence interval answers.
