An upper tail area should be found since the test statistic, z = 1.19, is positive. The area under the curve to the right of a z-value corresponds to the upper tail area. Recall that the standard normal table gives the area to the left of z-values and the entire area under the curve is 1. Therefore, the upper tail area will be the difference of the whole area, 1, and the area to the left of z = 1.19. Use the standard normal table to find the upper tail area for z = 1.19, rounding the result to four decimal places. area to the right of 1.19 = 1 - area to the left of 1.19 = 1 - x x =
