• -0.261

• 0.261

• 0.273

• -0.273

Answer explanation

Calculator is left-handed, so we need the left area:

1 - 0.603 = 0.397

invNorm(0.397, 0, 1) = -0.261

• 1.589

• 1.216

• 0.141

• 0.234

Answer explanation

0.888 is the area in the center. We need the left tail!

1 - 0.888 = 0.112

0.112/2 = 0.056

invNorm(0.056, 0, 1) = -1.589

Because this is two-tailed, there is a positive and negative 1.589.
