The sampling distribution is the probability distribution based on a random sample of some size.
The sampling distribution is the collection of all sample statistics from the population i.e;. Samples of same sizes drawn from a population.
so, option 'b' is correct

What is the sampling distribution of a statistic? A) The distribution of observations of the statistic for all possible sizes of samples from a population B) The distribution of all possible observations of the statistic for samples of a given size from a population C) The distribution of observations of a variable in a sample for a given value of the statistic

When we sketch a sampling distribution of means, we often assume it will be normal in its shape, especially with a large enough sample size used for sampling means, even if the population distribution of scores we drew samples from is not normal in its shape. What allows us to make this assumption?

Scores on the SAT mathematics section have a normal distribution with mean 4-500 and standard deviation o=100. a. What proportion of students score above a 550 on the SAT mathematics section? Round your answer to 4 decimal places. b. Suppose that you choose a simple random sample of 16 students who took the SAT mathematics section and find the sample mean x of their scores. Which of the following best describes what you would expect? The sample mean will be...

R Programming codes for the above questions?
In the notes there is a Central Limit Theorem example in which a sampling distribution of means is created using a for loop, and then this distribution is plotted. This distribution should look approximately like a normal distribution. However, not all statistics have normal sampling distributions. For this problem, you'll create a sampling distribution of standard deviations rather than means. 3. Using a for loop, draw 10,000 samples of size n-30 from a...

The two curves below represent the sampling distribution of the sample mean X for two different sample sizes: n = 256 and n = 576. In both cases the samples are selected from the same population. Note that the standard deviation for sampling distribution A is SD(X) = 8 and for sampling distribution B the standard deviation is SD(X) = 12. What is the standard deviation SD(X) of the population from which the samples are taken? A-8^2 B-(12+8)/2 C-13.86 D-12^2...
