Suppose that the hemoglobin levels among healthy females are normally distributed with a mean of 14 gm/dl. research shows that exactly 95% of healthy females have a hemoglobin level below 16.1 gm/dl. what is the standard deviation of the distribution of hemoglobin levels in healthy females? carry your intermediate computations to at least four decimal places. round your answer to at least two decimal places.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;
