A random sample of 700 units from a large

consignment showed that 200 were damaged. Find 95 % confidence interval for the
proportion of damaged unit in the consignment.



 The confidence interval is: (p∗zα2p∗⋅(1−p∗)n−−−−−−−−−−,p∗+zα2p∗⋅(1−p∗)n−−−−−−−−−−). Here p∗=200/700=0.286, 1−p∗=0.714, n=700, zα2=1.96. So C.I=(0.253,0.319
