Why is a binomial distribution a reasonable approximation of a sampling distribution for a population proportion when the population is large relative to the sample size?
Do not use normal approximation method. The question is asking
for exact binomial distribution method. Ans: 95%CI=(0.51,0.91)
3. In class we analyzed data on whether taller US presidential candidate won the election. Analyze the data for 1932-2012 below (note: Mitt Romney is 1 inch taller than Barrack Obama). Frequency 15 taller shorter construct 95% confidence interval for the proportion that taller US presidential candidates won the election based on exact binomial distribution. Show your work.
You intend to estimate a population proportion with a confidence interval. The data suggests that the normal distribution is a reasonable approximation for the binomial distribution in this case. Find the critical value that corresponds to a confidence level of 99%. (Report answer accurate to three decimal places with appropriate rounding) Za/2
You intend to estimate a population proportion with a confidence interval. The data suggests that the normal distribution is a reasonable approximation for the binomial distribution in this case. While it is an uncommon confidence level, find the critical value that corresponds to a confidence level of 91.9%. (Report answer accurate to three decimal places with appropriate rounding.) 23/2
You intend to estimate a population proportion with a confidence interval. The data suggests that the normal distribution is a reasonable approximation for the binomial distribution in this case. While it is an uncommon confidence level, find the critical value that corresponds to a confidence level of 81.2%. (Report answer accurate to three decimal places with appropriate rounding.) za/2 = ±
1. What is a sampling distribution? A) A distribution of respondent frequencies for all variables in a survey. B) A visual method for displaying statistics. C) A theoretical distribution of all possible sample values for the statistic in which we are interested. D) None of the above. 2. True or false, the Central Limit Theorem for sample means says that if larger and larger samples are drawn from the population, the distribution of the sample means will approximate a normal...

6. The sampling distribution of the sample proportion In 2007, about 30% of new-car purchases in California were financed with a home equity loan. [Source: "Auto Industry Feels the Pain of Tight Credit," The New York Times, May 27, 2008.] The ongoing process of new-car purchases in California can be viewed as an infinite population Define p as the proportion of the population of new-car purchases in California...

A random sample of size n = 60 is selected from a binomial distribution with population proportion p = 0.25. (a) What will be the approximate shape of the sampling distribution of p? O skewed to the right O skewed to the left O normal (b) What will be the mean and standard deviation (or standard error) of the sampling distribution of p? (Round your answers to four decimal places.) C standard deviation mean (c) Find the probability that the...
