"Six is a number perfect in itself, and not because God created the world in six days; rather the contrary is true. God created the world in six days because this number is perfect, and it would remain perfect, even if the work of the six days did not exist."  (St. Augustine, 354430)
Ancient Egyptian Mathematics: Papyrus is a form of paper made from a reed that grows along the banks of the Nile River. Four very ancient documents provide us information about the amazing mathematics of the Egyptians. (Two will be mentioned here; the other two were referenced in Assignment #74.) The Rollin Papyrus (ca 1350 B.C.): This document, now housed in the Louvre in Paris, supplies examples of Egyptian bread accounts. The Harris Papyrus (ca 1167 B.C.): A document prepared by Rameses IV to document the accomplishments of his father, Rameses III. These documents somehow managed to escape the ravages of time and human conquests. Other sources of knowledge about Egyptian mathematics comes from inscriptions on stone tombs and monuments.

A confidence interval for a proportion pcalculated from a sample statistics p(hat) has the form
95% confidence intervals are common when dealingwith proportions. In this case, z* = 1.96. (Sometimes z* = 2 isused.)
When you see scientifically conducted polls innewspapers, magazines, etc., the margin of error that is reportedapproximately 2 times the standard error calculated from the samplestatistics p(hat). This allows you to produce a 95% confidenceinternal for the population parameter p.
