When two births are randomly selected, the sample space for genders is bb, bg, gb, and gg. Assume that those four outcomes are equally likely. Construct a table that describes the sampling distribution of the sample proportion of girls from two births. Does the mean of the sample proportions equal the proportion of girls in two births? Does the result suggest that a sample proportion is 1 an unbiased estimator of a population proportion? For the entire population, assume the probability of having a boy is the probability of having a girl is, and this is not affected by how many boys or girls have previously been born. Determine the probabilities of each sample proportion. Sample proportion of girls ▼ Does the mean of the sample proportions equal the proportion of girls in two births? 1 O A. Yes, both the mean of the sample proportions and the population proportion are 4 Probability (Type integers or simplified fractions.)

Does the result suggest that a sample proportion is an unbiased estimator of a population proportion?
O A. No, because the sample proportions and the population proportion are the same.
O B. Yes, because the sample proportions and the population proportion are not the same.
O C. No, because the sample proportions and the population proportion are not the same.
D. Yes, because the sample proportions and the population proportion are the same.
