Problem 3) Lead concentrations in the eggshells of California condors have a mean of 1.8 and a standard deviation of 0.3 ppm. The contamination levels of eggshells are classified as "low" if the lead concentration is below 1.0 ppm, “moderate" if the lead concentration falls between 1.0 ppm and 2.4 ppm, and “high" the lead concentration is above 2.4. Assuming that the lead concentrations of eggshells follows a normal distribution, answer the following questions. (Hint* The categories of Low, Moderate, and High can help you identify the boundaries of each interval. For example, the boundaries of Low are – ∞ to 1.0.) ppm 13. What is the percentile of an eggshell with a lead concentration of 2.3 ppm? a. 81st b. 93rd с. 86th d. 95th 14. What lead concentration corresponds to the 79th percentile? a. 2.04 ppm b. 2.53 ppm с. 2.43 рpm d. 2.76 ppm
