Given a normal distribution with =4 and =2, what is the probability that a. Between what two X values (symmetrically distributed around the mean) are 95 % of the values? INSTRUCTIONS: Show all your work as to how you have reached your answer. Please don't simply state the results. Show graphs where necessary. 1. Draw the normal curve 2. Insert the mean and standard deviation 3. Label the area of 95% under the curve 4. Use Z to solve the unknown X values ( lower X and Upper X)
