For two populations of rabbits, R and S, the proportions of rabbits with white markings on their fur are given as pR and pS, res
BlackZzzverrR [31]

Answer:

The standard deviation is  \hat p_{R} -\hat p_{S} = \sqrt{\frac{\hat p_{R}(1-\hat p_{R})}{50} + \frac{\hat p_{S}(1-\hat p_{S})}{100} }

Step-by-step explanation:

The standard deviation of a sampling distribution is the standard error or a valuation of the standard deviation. Where statistic parameter is the mean it is referred to as the standard error of the mean.

The formula for standard deviation of a sampling distribution is as follows;

\hat p_{R} -\hat p_{S} = \sqrt{\frac{\hat p_{R}(1-\hat p_{R})}{n_R} + \frac{\hat p_{S}(1-\hat p_{S})}{n_S} }

Where;

{\hat p_{R}} = Sample proportion of rabbits with white markings from R

{\hat p_{S}} = Sample proportion of rabbits with white markings from S

n_R = Number of from R = 50

n_S = Number of from S = 100

Therefore, the standard deviation of the sampling distribution is given as follows;

\hat p_{R} -\hat p_{S} = \sqrt{\frac{\hat p_{R}(1-\hat p_{R})}{50} + \frac{\hat p_{S}(1-\hat p_{S})}{100} }.
