Calculate the 95% margin of error in estimating a population mean μ for the following values. (Round your answer to three decimal places.) n = 30, σ² = 3.9 Consider that for n = 30 and ² = 0.1, o² = 1.0, and o² = 1.7 the margins of error are 0.113, 0.358, and 0.467 respectively. Comment on how a larger population variance affects the margin of error. O As the population variance o² increases, the margin of error decreases. O As the population variance o² increases, the margin of error remains relatively constant. O As the population variance o2 increases, the margin of error also increases.
