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?© BrainMass Inc. brainmass.com October 9, 2019, 11:06 pm ad1c9bdddf
The solution provides step by step method for the calculation of sample size for normal distribution . Formula for the calculation and Interpretations of the results are also included.
