Section 17.3 Exercise 9An advocacy organization surveys 949 citizens of country A and 184 of them reported being born in another country. Similarly, 176 out of 1255 citizens of country B reported being foreign-born The researchers want to test if the proportions of foreign born are thesame in country B as in country A. Complete parts a through c below.a) What is the difference in the sample proportions, p, - P2, of foreign born residents from both countries? Assume p, is the proportion of foreign born residents from country A and p, is the proportion of foreign born residents from country BThe difference in the sample proportions, p, - P2, is(Round to three decimal places as needed.)Question Viewer

7.2.29-T Question Help An IQ test is designed so that the mean is 100 and the standard deviation is 19 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 99% confidence that the sample mean is within 6 IQ points of the true mean. Assume that o = 19 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. The required sample size is.

X 6.3.10 Question Help Three randomly selected households are surveyed. The numbers of people in the households are 2, 4, and 9. Assume that samples of size n = 2 are randomly selected with replacement from the population of 2, 4, and 9. Construct a probability distribution table that describes the sampling distribution of the proportion of odd numbers when samples of sizes n= 2 are randomly selected. Does the mean of the sample proportions equal the proportion of odd numbers in the population? Do the sample proportions target the value of the population proportion? Does the sample proportion make a good estimator of the population proportion? Listed below are the nine possible samples. 2,2 2,4 2,9 4,2 4,4 4,9 9,2 9,4 9,9 Construct the probability distribution table. Sample Proportion Probability (Type an integer or fraction.)
