For the following core project, be sure to show the mathematical process used to complete each part of the project. 1. IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. a) Draw a sketch of and label a graph that shows all the information relevant to the problem. b) Find the IQ score of someone who scores below exactly 23% of the population. First draw and label an approximate sketch of the distribution. If working this by hand, show all work. If using calculator functions, write out the command you enter. Round to two decimal places
