WebThe z-score for our apple is (110-100) / 15 = 0.67. The truncated z-table below shows the area for our z-score. By looking at the intersection for 0.6 and 0.07, the z-table indicates that the area under the curve is 0.74857. This value indicates that 74.857% of all apple weights will be lower than our apple weight of 110 grams. WebDec 11, 2024 · Using a Z score table or a calculator: P (Z= -1.2) = .1151.
