Solving a sample size calculation problem
How does the bell-shaped curve for the sampling distribution of sample means for samples of size n = 120 compare to the bell-shaped curve for the sampling distribution of sample means for samples of size n = 95?
Answer: A curve with a sample size of 120 will fit a perfect curve more accurately than a curve with a sample size of 95. As the sample size is increased, the distribution becomes more precise.
BUT QUESTION--What happens to the variability in larger samples that creates that constriction in the bell?© SolutionLibrary Inc. solutionlibary.com 9836dcf9d7 https://solutionlibrary.com/statistics/data-collection/solving-a-sample-size-calculation-problem-7euu
