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 a normal sampling distribution): (Use 3 decimal places) (a) A 95% confidence interval from a sample of size 10. Quantile: Standard deviation of sample mean: Margin of Error: (b) A 99% confidence interval from a sample of size 29. Quantile: Standard deviation of sample mean: Margin of Error: (c) A 80% confidence interval from a sample of size 3. Quantile: Standard deviation of sample mean: Margin of Error:
