3. A drug comes in the form of a liquid suspension with a mean concentration of 32 mg/ml. However, the concentration of the suspension is not completely uniform, having a standard deviation of 1.5 mg/ml, based on the random distribution of the drug particles suspended in the liquid solution. (10 marks) a. If one mL of the suspension is randomly drawn out of the bottle, what is the probability that the concentration is less than 30 mg/ml? b. If a tsp (5 ml) of the suspension is randomly drawn out of the bottle, what is the probability that the amount of active drug is the suspension will be between 150 mg and 165 mg? 2. The concentration of blood hemoglobin in middle aged adult females is normally distributed with a mean of 13.5 g/dl and a standard deviation of 0.86 g/dl. If a middle-aged adult female is randomly selected, determine the probability that her blood hemoglobin concentration will be (12 marks) a. Less than 12 g/dl b. Greater than 14.5 g/dl c. Between 12.1 and 15.1 g/dl d. Determine the hemoglobin levels corresponding to the 10th percentile e. Determine the hemoglobin levels corresponding to the 90th percentile f. Middle 85% of middle-aged adult female hemoglobin levels
