Answer to Question #309038 in Statistics and Probability for Jowem

Question

Find the corresponding area between z = 0 and each of the following.

1. Z = 0,85

2. Z = 1.27

3. z = 2.86

4. Z = -1.05

5. Z = -2.96

Answer 1

Corresponding area between z=0 and z-score is probability that standard normal distribution variable will take value between z-score and 0, so

1 $P(0<Z<0.85)=0.30234$

2 $P(0<Z<1.27)=0.39796$

3 $P(0<Z<2.86)=0.49788$

4 $P(-1.05<Z<0)=0.35314$

5 $P(-2.96<Z<0)=0.49846$
