Question

find the area under the standard normal curve that lies between the following z-values. round the answers to four decimal places.
part: 0 / 2
part 1 of 2
(a) find the area under the standard normal curve that lies between z = -2.32 and z = -0.82.
the area between z = -2.32 and z = -0.82 is

Explanation:

Step1: Recall the standard normal distribution properties

The area under the standard normal curve between two z - values \( z_1 \) and \( z_2 \) (where \( z_1

Step2: Find \( P(Z < - 0.82) \) and \( P(Z < - 2.32) \)

We can use the standard normal table (z - table) to find these probabilities.

  • For \( z=-0.82 \): Looking up in the z - table, the row for \( - 0.8 \) and column for \( 0.02 \), we get \( P(Z < - 0.82)=0.2061 \).
  • For \( z = - 2.32 \): Looking up in the z - table, the row for \( - 2.3 \) and column for \( 0.02 \), we get \( P(Z < - 2.32)=0.0102 \).

Step3: Calculate the area between \( z=-2.32 \) and \( z = - 0.82 \)

Using the formula \( P(-2.32<Z < - 0.82)=P(Z < - 0.82)-P(Z < - 2.32) \)
Substitute the values we found: \( 0.2061 - 0.0102=0.1959 \)

Answer:

\( 0.1959 \)
