Answer:
The third is quartile is 0.67
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.
