Question

following graph, if z = 1.74. A. Area 1 = (.5000 - 3078), Area 2 = 3078, Area 3= 3078, Area 4= (.5000 - 3078), so Area 1 + Area 2 + Area 3 + Area 4 = 1.000 Area 1= 4591, Area 2= (.5000 - 4591), Area 3= (.5000 - 4591), Area 4= 4591, so Area 1 + Area 2 + Area 3+ Area4 = 1.000 Area 1 = (.5000 - 4591), Area 2 = 4591, Area 3 = 4591, Area 4 = (.5000 - 4591), so Area 1 + Area 2 + Area 3 + Area 4 = 1.000 Area 1 = (1.000 - 4591), Area 2 = 4591, Area 3 = 4591, Area 4 = (1.000 - 4591), so Area 1 + Area 2 + Area 3 + Area 4 = 1.000

Explanation / Answer

Area 1 = P(Z< -1.74) =0.0409 = 0.5 -0.4591

Area 4 = P(Z > 1.74) = 0.0409 == 0.5 -0.4591

Area 1 +Area 2 = 0.5

Area 3 +Area 4 = 0.5

hence option C) is correct
