Area to Z-Score Practice

What shape is a normal distribution curve?

• Half curve
• Round curve
• Bell curve
• Square curve

If the shaded area under the curve is .85, what is the other missing portion of the curve?

• .26
• .15
• .30
• .17

The normal curve is symmetrical about the mean.

• True
• False

Find the value of k
P(Z> k) = 0.2327

• -0.24
• -0.75

Find the value of k
P( Z ≤ k ) = 0.8264

• -0.06
• 0.06
• -0.94
• 0.94

Find the value of k
P(Z > k ) = 0.75

• -0.67
• 0.67
• -0.33
