    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.
