The random variable X is normally distributed. Also, it is known that P(X 186) = 0.03. a. Find the population mean // if the population standard deviation O = 11. Note: Round "z" value to 3 decimal places and final answer to 2 decimal places. Mean b. Find the population mean / if the population standard deviation q = 22. Note: Round "z" value to 3 decimal places and final answer to 2 decimal places. Mean c. Find the population standard deviation O if the population mean / = 165. Note: Round "z" value to 3 decimal places and final answer to 2 decimal places. Standard deviation d. Find the population standard deviation O if the population mean / = 153. Note: Round "z" value to 3 decimal places and final answer to 2 decimal places. Standard deviation
