Answer:
E = 0.0083/0.008
Step-by-step explanation:
Substituting x1 and n1 for their provided values, p1 = 0.86842105263157894736842105263158.
Using the same logic, p2 = 0.85148514851485148514851485148515.
q1 = 1 - 0.86842105263157894736842105263158 = 0.13157894736842105263157894736842
q2 = 1 - 0.85148514851485148514851485148515 = 0.14851485148514851485148514851485
(p1 * q1) / n1 = 0.00300699810467998250473830004374.
(p2 * q2) / n2 = 0.00125206129082666133489145405081.
0.00300699810467998250473830004374 + 0.00125206129082666133489145405081 = 0.00425905939550664383962975409455.
Square root of 0.00425905939550664383962975409455 is 0.06526146945561863334735397268823.
Substituting 1.96 for z, 1.96 * 0.00425905939550664383962975409455 is 0.00834775641519302192567431802532.
E = 0.0083/0.008
