null hypothesis: no difference between algorithms

alternate hypothesis: newer has lower mean completion time than current one

it is an one tailed test

critical value at 0.01% significant level=2.33

Z=(x1-x2)/(s1^2/n1+s2^2/n2)^0.5

=0.17/0.747=0.22

given pair satisfy null hypothesis ,since value is less than critical value

reject null hypothesis if limits are

above upper limit=1.74

below lower limit= -1.74
