Sketch the area under the standard normal curve over the
indicated interval and find the specified area. (Round your answer
to four decimal places.) The area between * z* =
−1.31 and

Answer #1

1)

Shaded region in the curve below is the area to the left of z = -0.54.

Area to the left of z = -0.54 is

P(z < -0.54) = 0.2946 (From statistical table of negative z values)

**The area to the left of z = −0.54 is 0.2946**

2)

Shaded region in the curve below is the area between
* z* = −1.31 and

Area between * z* = −1.31 and

P(-1.31 < z < 1.97) = P(z < 1.97) - P(z < -1.31)

= 0.9756 - 0.0951 (From statistical table of z values)

= 0.8805

**The area between z = −1.31 and
z = 1.97 is 0.8805**
