SOLVED: Suppose the population standard deviation is 1.91. Compute the correct quantile, the correct population standard deviation for the sample mean, and the correct margin of error for each confidence interval (assuming the sample mean has normal sampling distribution): (Use 3 decimal places)(a) A 95% confidence interval from sample of size 19 Quantile: Standard deviation of sample mean: Margin of Error:(b) A 99% confidence interval from a sample of size 25. Quantile: Standard deviation o
