Detailed explanation-1: -The prevalence of sampling errors can be reduced by increasing the sample size. As the sample size increases, the sample gets closer to the actual population, which decreases the potential for deviations from the actual population.
Detailed explanation-2: -Sample Size and Variability A larger sample size or lower variability will result in a tighter confidence interval with a smaller margin of error. A smaller sample size or a higher variability will result in a wider confidence interval with a larger margin of error.
Detailed explanation-3: -As the sample size increased the standard error decreased. Also note how the shape of the sampling distribution changed. With the smaller sample size there were large gaps between each possible sample proportion.
Detailed explanation-4: -As the sample size gets larger, the dispersion gets smaller, and the mean of the distribution is closer to the population mean (Central Limit Theory). Thus, the sample size is negatively correlated with the standard error of a sample.
