If you choose 40 random employees from the corporation, the standard error would equal 6/Square root of 40 = .95 days.

a) How many independent network servers would be needed if each has 99 percent reliability? independent failure rate = 0.01 combined failure rate = 0.00001 0.01^n = 0.00001 10^(-2n) = 10^-5 -2n = -5 n = 2.5 servers needed = 3 b) If each has 90 percent reliability? independent failure rate = 0.1 combined failure rate = 0.00001 0.1^n = 0.00001 10^(-n) = 10^-5 -n = -5 n = 5 servers needed = 5 5.74 Refer to the contingency table shown below. (a) Calculate each probability (i–vi) and explain in words what it means. (b) Do you see evidence that smoking and race are not independent?
