The assets (in billions of dollars) of the four wealthiest people in a particular country are 39, 33, 29, 10. Assume that samples of size n = 2 are randomly selected with replacement from thispopulation of four values.a.

A random sample is one in which the A. probability that an item is selected for the sample is the same for all population items. B. Population items are selected haphazardly by experienced workers. C. Items to be selected from the population are specified based on expert judgement. D. Probability of selecting a population item depends on the item's data value.
K Determine 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 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 an unbiased estimator of 1 1 the probability of having a girl is, and this is not affected by how many boys or girls have previously been a population proportion? For the entire population, assume the probability of having a boy is 2' born. Sample proportion of girls Does the mean of the sample proportions equal the proportion of girls in two births? 14 O A. Yes, both the mean of the sample proportions and the population proportion are OB. No, the mean of the sample proportions and the population proportion are not equal. 1 O c. Yes, both the mean…

The accompanying table describes results from groups of 8 births from 8 different sets of parents. The random variable x represents the number of girls among 8 children. Complete parts (a) through (d) below. E Click the icon to view the table, a. Find the probability of getting exactly 1 girl in 8 births. (Type an integer or a decimal. Do not round.) Probability distribution for x b. Find the probability of getting 1 or fewer girls in 8 births. Number of Girls x (Type an integer or a decimal. Do not round.) P(x) 0.002 0.019 0.119 c. Which probability is relevant for determining whether 1 is a significantly low number of girls in 8 births: the result from part (a) or part (b)? 1 O A. Since the probability of getting more than 1 girl is the complement of the result from part (b), this is the relevant probability. 3 0.189 O B. Since the probability of getting 1 girl is the result from part (a), this is the relevant probability. 0.342 5 0.189 OC. Since the probability of getting 0 girls is…

K The population of ages at inauguration of all U.S. Presidents who had professions in the military is 62, 46, 68, 64, 57. Why does it not make sense to construct a histogram for this data set? Choose the correct answer below. O A. With a data set that is so small, the true nature of the distribution cannot be seen with a histogram. OB. There must be an even number of data values in the data set to create a histogram. OC. This data set would yield a histogram that is not bell-shaped. O D. Adequate class boundaries for a histogram cannot be found with this data set.
