(2) Determine the areas under the normal curve given the mean of the distribution µ = 80 and o = 5.5, and the given value of the random variable x and the probability function in each item below. Write down the probability function described in each and draw the normal curve with the proper shaded area of interest. 5. The area of interest is above the score x = 69.42. 6. The area of interest is below the score x = 83.42.
