Consider a population with a known standard deviation of 11 2. In order to compute an interval estimate for the population mean, a sample of 43 observations is drawn [You may find it useful to reference the table.) a. is the condition that 10 point Shoped X is normally distributed satisfied?? Yes No chool H b. Compute the margin of erfor at a 90% confidence level (Round intermediate calculations to at least 4 decimal places. Round" value to 3 decimal places and final answer to 2 decimal places.) Pre Margin of error References c. Compute the margin of error at a 90% confidence level based on a larger sample of 470 observations. (Round Intermediate calculations to at least 4 decimal places. Round "r" value to 3 decimal places and final answer to 2 decimal places.) Margin of error d. Which of the two margins of error will lead to a wider confidence interval? W
