Question 4 0.5 pt Assume that a vertical line is drawn through a normal distribution at each of the following z-score locations. In each case, determine whether the tail is on the left side or the right side of the line and find the proportion of the distribution that is located in the tail. a. z = +1.80 b. z = +0.60 C. Z = -0.40 d. z = -1.25 Hint: These problems can be solved easily if you draw a normal curve (no need to show me) with u =0 at the center and place the value z-score on the left or right side of the mean depending on the sign. Then you need to refer to the Unit normal table to find the proportion (or percentage)
