KDetermine the probabilities of each sample proportion.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 ofthe 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 an unbiased estimator of11the probability of having a girl is, and this is not affected by how many boys or girls have previously beena population proportion? For the entire population, assume the probability of having a boy is2'born.Sample proportion of girlsDoes the mean of the sample proportions equal the proportion of girls in two births?14O A. Yes, both the mean of the sample proportions and the population proportion areOB. No, the mean of the sample proportions and the population proportion are not equal.1O c. Yes, both the mean of the sample proportions and the population proportion are21OD. Yes, both the mean of the sample proportions and the population proportion are3...The quesDoes 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 not the same.O B. Yes, because the sample proportions and the population proportion are not the same.OC.

Refer to the following scenario. A government official is in charge of allocating social programs throughout the city of Vancouver. He will decide where these social outreach programs should be located based on the percentage of residents living below the poverty line in each region of the city. He takes a simple random sample of 120 people living in Gastown and finds that 21 have an annual income that is below the poverty line. For each of the following statements, specify whether the statement is a correct interpretation of the 95% confidence interval for the true proportion of Gastown residents living below the poverty line. A. 17.50% (21/120) of Gastown residents are living below the poverty line. ? B. There is a 95% probability that the true proportion of Gastown residents who are living below the poverty line equals 21/120. C. If another random sample of 120 Gastown residents is drawn, there is a 95% probability that the sample proportion of Gastown residents who are living below…
