According to a polling organization, 22% of adults in a large region consider themselves to be liberal. A survey asked 200 respondents to disclose their political philosophy: Conservative, Liberal, Moderate. Treat the results of the survey as a random sample of adults in this region. Do the survey results suggest the proportion is higher than that reported by the polling organization? Use an a = 0.01 level of significance. E Click the icon to view the survey results. Because npo (1- Po) =| > 10; the sample size is less than 5% of the population size, and the sample is given to be random, the requirements for testing the hypothesis satisfied. are (Round to one decimal place as needed.)
In 2016 the Better Business Bureau settled 84% of complaints they received in the United States. Suppose you have been hired by the Better Business Bureau to investigate the complaints they received this year involving new car dealers. You plan to select a sample of new car dealer complaints to estimate the proportion of complaints the Better Business Bureau is able to settle. Assume the population proportion of complaints settled for new car dealers is 0.84, the same as the overall proportion of complaints settled in 2016. Use the z-table. a. Suppose you select a sample of 200 complaints involving new car dealers. Show the sampling distribution of p. E(p) (to 2 decimals) (to 4 decimals) b. Based upon a sample of 200 complaints, what is the probability that the sample proportion will be within 0.04 of the population proportion (to 4 decimals)? probability : = c. Suppose you select a sample of 460 complaints involving new car dealers. Show the sampling distribution of p. E(F) (to 2…

To receive a particular professional designation, an individual must pass a specific professional exam. A preparatory course is available, and individuals who take the preparatory course, pass the professional exam 90% of the time, while individuals who do not take the preparatory course only pass the exam 20% of the time. Suppose 55% of individuals who take the professional exam have taken the preparatory course. What percent of individuals who take this exam pass? The percent of individuals passing is percent. Do NOT use the % sign as part of your answer, and do NOT round your answer.
