Q15 4 Points You are a Materials Scientist managing a team responsible for the quality of silicon carbide ceramic components used in high temperature kilns. You know that the density of these silicon carbide parts is normally distributed and has a mean of 2.75 g/cm3 and a standard deviation of 0.12 g/cm3. You need to quickly determine whether some density measurements made by a new employee are unusual or not. Use the 68-95-99.7% Rule to answer the questions. Q15.1 1 Point 84% of all specimens have densities less than what value? Enter your answer here Save Answer Q15.2 1 Point The new employee tells you that the component they just made has a density of 2.51 g/cm3. What percentage of components are denser? Enter your answer here Save Answer Q15.3 1 Point What is the probability that a randomly-chosen specimen has a density is between 2.63 and 2.87 g/cm3? Enter your answer here Save Answer Q15.4 1 Point If the acceptable range of densities is (2.75 - c, 2.75 + c), for what value of c would 95% of all specimens have acceptable density?
