<h3>What is a z-score?</h3>
The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The probability for the z-score is greater than or equal to 1.4 is given as
P(z ≥ 1.4) = 1 - P( z < 1.4}
P(z ≥ 1.4) = 1 - 0.91924
P(z ≥ 1.4) = 0.08076
P(z ≥ 1.4) = 8.076 %
