Extracted text: A simple random sample of 14 observations is derived from a normally distributed population with a known standard deviation of 2.4. [You may find it useful to reference the z table.] a. Is the condition that X is normally distributed satisfied? O Yes O No b. Compute the margin of error with 99% confidence. (Round intermediate calculations to at least 4 decimal places. Round "z" value to 3 decimal places and final answer to 2 decimal places.) Margin of error 35.42 c. Compute the margin of error with 95% confidence. (Round intermediate calculations to at least 4 decimal places. Round "z" value to 3 decimal places and final answer to 2 decimal places.)
