Suppose that a highway patrol person wants to estimate what proportion of all drivers drive over the speed limit, and she wants to be able to assert with probability of at least 0.95 that its error will not exceed 0.07 . How large a sample will be needed if she knows that the true proportion lies somewhere on the interval from 0.6 or 0.7 ?
A) $n=165$
B) $n=196$
C) $n=189$
D) $n=188.2$
