(Use a comma to separate answers as needed. Round to two decimal places as needed.)
Sketch the normal curve.
1. Find the area between z= -1.5 and z= -2.5
2. Find the area between z= -1.35 and z=2.95
3. Find the area to the left of z= 2.32
4. Find the area to the right of z= -1.8
Match each P-value with the graph that displays its area without performing any calculations. Explain your reasoning.
P=0.2776
and
P=0.0212.
Graph A
(a) z=−2.03
A graph labeled (a) has a normal curve above and centered on the 0 of a horizontal axis labeled from negative 3 to 3 in increments of 1. A vertical line segment extends from the curve to the horizontal axis at the labeled point z is equal to negative 2.03. The area under the curve to the left of z is shaded.
Graph B
(b) z=−0.59
A graph labeled (b) has a normal curve above and centered on the 0 of a horizontal axis labeled from negative 3 to 3 in increments of 1. A vertical line segment extends from the curve to the horizontal axis at the labeled point z is equal to negative 0.59. The area under the curve to the left of z is shaded.
