Describe about the shape of sampling distribution.

Suppose the true proportion of voters in the county who support a specific candidate is 0.43. Consider the sampling distribution for the proportion of supporters with sample size n = 127.   What is the mean of this distribution?   What is the standard error of this distribution?   Please round to at least 3 significant figures.

Define Random Sampling and the Distribution of the Sample Average?

Which BEST describes the shape of the distribution?            Uniform       Skewed right       Skewed left       Symmetrical

Suppose that 80% of apples are worm-free. Explain why it would not be unusual to find 84% of a simple random sample of 120 apples to be worm-free but it would be unusual to find 84% of a simple random sample of 480 apples to be worm-free. Use facts about the sampling distributions of sample proportions when n = 120 and when n = 480 to support your explanation.

What is another kind of sampling error you might see in a poll besides random sampling error?

8. For a right-skewed distribution, which is greater: the mean or the median? Give a brief but specific explanation of your reasoning. Sketch a right-skewed distribution, labeling the mean and median for the distribution of a population.

Describe the shape of both sampling distribution.
