Use the given shaded area (0.7035) in the middle of the standard normal distribution and the given z-score (-1.2) to find the missing z-score. The shaded region is not symmetric about z = 0. Round your final answer to two decimal places. Shaded Area = 0.7035 -4 -3 222 -2 -1.2 Upper z-score= -1 0 2 3 4 = a
