Complete the problems below. Show some ofthe steps and explain theanswer. Type/write up the answers to the questions. For example, show z-scores that computed, tell how you get the % answer (table? calculator?), and if there were other math steps to get your answer. In other words, give some proof.

Scenario: The hemoglobin (a substance in the blood that carries oxygen) level (gm/dL) in Swedish men aged 35-50 follows an approximately normal distribution. The population mean is 15.5 gm/dL and the standard deviation is 1.2 gm/dL.

1. What percent of Swedish men have a hemoglobin that is below 13.2gm/dL? Round your answer to 2 decimal places (eg XX.xx%)
2. What percent of Swedish men have a hemoglobin that is at or below 17.4gm/dL? Round your answer to 2 decimal places.
3. What percent of Swedish men have a hemoglobin that is above 18gm/dL? Round your answer to 2 decimal places.
4. What percent of Swedish men have a hemoglobin that is between 12.4 and 16.7? Round your answer to 2 decimal places.
5. The lowest 25% of hemoglobin levels in Swedish men is at or below what number? Round your answer to 1 decimal place.
