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.

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.

3. QUESTION CONSIDER THE FOLLOWING MULTIPLE CHOICE QUESTIONS CIRCLE YOUR SELECTION CLEARLY: EG a. ONE b. Two c.) THREE A certain brand of jelly beans are made so that each package contains about the same number of beans. The filling procedure is not perfect, however. The packages are filled with an average of 375 jelly beans, but the number going into each bag is normally distributed with a standard deviation of 8. Yesterday, Jane went to the store and purchased four of these packages in preparation for a Spring party. Jane was curious, and she counted the number of jelly beans in these packages - her four bags contained an average of 382 jelly beans. 3.1 In the above scenario, which of the following is a parameter? a. The average number of jelly beans in Jane's packages, which is 382 b. The average number of jelly beans in Jane's packages, which is unknown c. The average number of jelly beans in all packages made, which is 375 d. The average number of jelly beans in all packages made,…
