Page 1: Normality test

We can now interpret the result.

The test statistics are shown in the third table. Here two tests for normality are run. For dataset small than 2000

elements, we use the Shapiro-Wilk test, otherwise, the Kolmogorov-Smirnov test is used. In our case, since we have

only 20 elements, the Shapiro-Wilk test is used. From A, the p-value is 0.316. We can reject the alternative

hypothesis and conclude that the data comes from a normal distribution.
