Question

When two Dirts are randomly selected, the sample space rol genders is DD, Dg. 90, ana 99. Assume that those Tour 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 the probability of having a girl is and this is not affected by how is an unbiased estimator of a population proportion? For the entire population, assume the probability of having a boy is many boys or girls have previously been born. Determine the probabilities of each sample proportion. Sample proportion of girls Probability (Type integers or simplified fractions.)

Answer 1
