MY NOTES PRACTICE ANOTHER A polling organization polls n = 100 randomly selected registered voters to estimate the proportion of a large population that intends to vote for Candidate Y in an upcoming election. Although it is not known by the polling organization, p = 0.7 is the actual proportion of the population that prefers Candidate Y. (a) Give the numerical value of the mean of the sampling distribution of p. Mean = (b) Calculate the standard deviation, s.d., of the sampling distribution of p. (Round your answer to the nearest hundredth.) s.d. = (c) Use the Empirical Rule to find values that fill in the blanks in the following sentence. (Round all answers to the nearest hundredth.) In about 99.7% of all randomly selected samples of n = 100 from this population, the sample proportion preferring Candidate Y will be between and You may need to use the appropriate table in the Appendix of Tables to answer this question.
