The Providence Computer Supply Company knows that 20% of its computers will require warranty repairs within one month of shipment. In a typical month, 279 computers are shipped.

Find the mean and standard deviation of the number of shipped computers that requrie warranty repairs within one month of shipment. I say to find the number of computer shipped you multiply 279 by 20% which is 55.8. I don't know what to do after that.

The next part of this problem is For a typical month in which 279 computers are shipped, what would be an unusually low figure for the number of computers requiring warranty repaire within one month of shipment? What would be an unusually high figure for the number of computers requrieing warranty repair witin one month of shipment? How did you obtain these numbrs?
