Question

For the standard normal curve , find the z-score that corresponds to the third quartile answer??

Answer 1

Answer:

The third is quartile is 0.67

Step-by-step explanation:

Explanation:-

• The Z- score of the normal distribution is = x-μ /σ

finding the z-score of the third quartile

• The variance σ^2 = 0.25 is small the curve of the curve is tall and thin, concentrated the value 'μ'

• The standard normal distribution of the first quartile is -0.67 ( using 0.25)

• The third quartile is 0.67. this means that for normally data, one half of the data is with in 2/3 of a standard deviation unit of the mean.
