We will use a left-tail style table to determine the area, which gives cumulative areas to the left of a specified z. Since we are looking for the area to the left of the given z we can read the table value directly. Since z = 0.49 is positive An excerpt from this table is given. I Z we will look at the portion of the Standard Normal Distribution Table for which the z values are positive. 0.05 0.06 0.07 0.08 0.09 0.4 0.6736 0.6772 0.6808 0.6844 0.6879 0.5 0.7088 0.7123 0.7157 0.7190 0.7224 For the z value 0.49, we have 4 in the tenths place, and 9 in the hundredths place. Therefore, the area of the shaded region is found by looking at the number in the row labeled 0.4 and the column labeled 0.09 Reading the table in this way indicates that the area to the left of z = 0.49 is 0.49 X
