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.

Random samples of size 525 are taken from an infinite population whose population proportion is 0.3. The standard deviation of the sample proportions (i.e., the standard error of the proportion) is Select one: a. 0.0004 b. 0.0200 c. 0.2100 d. 0.3000

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...

2. Suppose a sample of size 40 is taken from a population with proportion 0.79. Find the standard error of the sampling distribution. Check whether the Central Limit Theorem applies to the sampling distribution. Based on proportion, what can you say about the shape of the sampling distribution?

uppose that the proportion of successes in a population is ? and that a very large simple random sample of size ? is obtained from that population. What does the central limit theorem say about the distribution of the sample proportion? The sample proportion has mean equal to ? and standard deviation equal to ?(1−?)?⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯√. The sample proportion is approximately normally distributed if the sample is large enough. The sample proportion is binomially distributed with parameters ? and ?. The...
