In 2016 the Better Business Bureau settled 77% of complaints they received in the United States. Suppose you have been hired by the Better Business Bureauto investigate the complaints they received this year involving new car dealers. You plan to select a sample of new car dealer complaints to estimate theproportion of complaints the Better Business Bureau is able to settle. Assume the population proportion of complaints settled for new car dealers is 0.77, thesame 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(F)(to 2 decimals)(to 4 decimals)%3Db. Based upon a sample of 200 complaints, what is the probability that the sample proportion will be within 0.07 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 decimals)(to 4 decimals)d. Based upon the larger sample of 460 complaints, what is the probability that the sample proportion will be within 0.07 of the population proportion (to 4decimals)?probability =e. As measured by the increase in probability, how much do you gain in precision by taking the larger sample in part (d)?The probability of the sample proportion being within 0.07 of the population mean is increased by(to 3 decimals). There is a gain in precision by- Select your answerv the sample size.

No written by hand solution The Coca-Cola Company reported that the mean per capita annual sales of its beverages in the United States were 459 eight-ounce servings (Coca-Cola Company website, February 25, 2017). Suppose you are curious whether the consumption of CocaCola beverages is higher in Atlanta, Georgia, the location of Coca-Cola’s corporate headquarters. A sample of 61 individuals from the Atlanta area showed a sample mean annual consumption of 479.5 eight-ounce servings with a standard deviation of s = 90 ounces. Using α = .01, does the sample support the conclusion that means annual consumption of Coca-Cola beverage products is higher in Atlanta? Use both the critical value and p-value approach to test the hypothesis that H0: µ >459 in Atlanta vs. the 1-sided alternative. 7.
