Question

Question Help 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 samp proportions equal the proportion of girls in two births? Does the result suggest that a sample proportion is 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 not affected by how many boys or girls have previously been born Determine the probabilities of each sample proportion. and this is Sample proportion of girls Probability (Type integers or simplified fractions.) Does the mean of the sample proportions equal the proportion of girls in two births? 1 OA. Yes, both the mean of the sample proportions and the population proportion are 2 O B. No, the mean of the sample proportions and the population proportion are not equal. O C. Yes, both the mean of the sample proportions and the population proportion are O D. Yes, both the mean of the sample proportions and the population proportion are Click to select your answer(s).

Answer 1

The probability distribution of proportion of girls in two births will be:

Sample proportion of girls	Probability
0	1/4
0.5	1/2
1	1/4

Does the mean of sample proportions equal to the proportion of girls in two births? Option A is correct.
