B. Use the mean and standard deviation for the 65 closing prices in the printout above as estimates of the mean and standard deviation found in the population of all closing prices. Suppose also that the closing prices in the population are normally distributed (regardless of what your analysis in part a indicated). Find the proportion of all closing prices that would fall between $10 and $50 in the population. I want you to show your work. To receive full credit, you should include pictures of the normal curve (labeled with both x and z-values) with the pertinent probabilities shaded in the picture.
