Buragratz Snak Haus compared their sales of hamburger per day at two locations. The mean number of sold hamburgers for 30 randomly selected days at the Fairview site was 87.65 and the standard deviation was 9.5. On the other hand, the random sample of 30 days at the Palmera site was 85.15 and the standard deviation was 15.2. Is there a difference in the mean number of hamburgers sold per day at two locations? Use 0.01 level of significance.

P.S. Please show a step-by-step computation, that would be much appreciated. Thank you.
