A. Suppose you take a sample of size n from a population and calculate a statistic from that sample. The statistic could be a sample proportion p, a sample mean x, or another statistic. Then suppose we repeat this process over and over again until we find all possible samples of size n from the population (this is a theoretical idea) and we calculate the same statistic from 1. each sample. The collection of all of the statistics calculated is...

A manufacturer of computer monitors estimates that 4 percent of all the monitors manufactured have a screen defect. Let pd represent the population proportion of all monitors manufactured that have a screen defect. For the sampling distribution of the sample proportion for samples of size 100, μPˆd=0.04. Which of the following is the best interpretation of μPˆd=0.04 ? For all samples of size 100, the mean of all possible sample proportions of monitors manufactured that have a screen defect is...

List all possible samples of size n=3, with replacement, from the population (1,3,5). Calculate the mean of each sample. Construct a probability distribution of the sample means and compute the mean, variance, and standard deviation of the sample means and compare to the mean, variance, and standard deviation of the population.

Consider taking samples of size 100 from a population with proportion 0.33. Is the sample size large enough for the Central Limit Theorem to apply so that the sample proportions follow a normal distribution? a) Yes, np and n(1-p) both >=10. b) No, np and n(1-p) both >=10. c) Yes, np and n(1-p) both >=100. d) No, 100 is never large enough.
