According to a statistical journal, the average lengths of a newborn is 19.6 inches with a standard deviation of 1.2 inches. The distribution of lengths is approximately Normal. What is the probability that a newborn baby will have a length of 18 inches or less? (Please include steps)

9.18%

Step-by-step explanation:

First, find the z-score.

z = (x − μ) / σ

z = (18 − 19.6) / 1.2

z = -1.33

Use a chart or calculator to find the probability:

P(Z < z) = 0.0918

you are saying it as if a fact, not a question, but yes, you would be correct? ; )

step-by-step explanation:

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
