Suppose that 25% of all males in a population are carriers of a certain infectious disease \\( (p_1= 0.25) \\) and that 28% of all females in the population are carriers \\( (p_2= 0.28). \\) researchers who don’t know these actual numbers are interested in estimating the difference by using random samples of 100 males and 100 females to find \\( \hat p_1−\hat p_2 \! \\) .
the standard deviation of the sampling distribution of \\( \hat p_1−\hat p_2 \\) is:
a)0.062.
b)0.004.
c)0.073.
