They work to support clean air. clean water and healthy communities with an emphasis on pointing out water concerns in Communities across the planet. Flint. Michigan has a known problem with an excess of lead in their drinking waterwhich is very harmful to the health of the people in the community. especially Children. The blood lead level in children in Flint during the peak of the water crisis [2015) is known to be approximately normally distributed with a mean of 1.31 micrograms per deciliterwith a standard deviation of 0.030 micrograms per deciliter. Assume that our interest is in probabilities about the blood lead level of a random child in Flint in the year 2015. Question 19 1 pts Pick the equation most appropriate to deal with the problem above.
