Gauthmathier9136Grade 12 · 2021-05-10 Answer Explanation Thanks (84) Does the answer help you? Rate for it! What is the standard error of the mean if the sample size is 25?Thus, for a sample of N = 25 and population standard deviation of s x = 100, the standard error of the mean is 100/5 or 20.
What will happens to the shape of a sampling distribution of samples means as sample size increases?In other words, as the sample size increases, the variability of sampling distribution decreases. Also, as the sample size increases the shape of the sampling distribution becomes more similar to a normal distribution regardless of the shape of the population.
What happens to the shape of a sampling distribution of sample means as the sample size n increases Quizizz?Q. What happens to the shape of a sampling distribution of sample means as n increases? It becomes narrower and bimodal.
What sample size for a sampling distribution will have the smallest standard deviation?From the above formula, we can infer that the standard error is inversely related to the sample size for a given population standard deviation. Hence, among the given options, the option with the highest sample size (i.e. n = 1,000) will yield the smallest standard deviation to the statistic.
