WebNormality test. One of the most common assumptions for statistical test procedures is that the data used must be normally distributed. For example, if a t-test or an ANOVA is to be calculated, it must first be tested whether the data or variables are normally distributed. If the normal distribution of the data is not given, the above procedures cannot be used and … WebAccording to the Z-Score table, we get P (Z < 1.25) = 0.8944 (area to the left of the Z-Score), this indicates 89.44% of students scored less than 75. But we need to find the proportion of students who scored more than 75, P (Z > 1.25) which lies to the right of the calculated Z-Score.
