The Shapiro-.Wilk test determines if a given dataset is Spacing normally distributed. At Least Null hypothesis: The data are normally distributed Before Paragraph Alternative hypothesis: The data are not normally distributed. At the 5% level of significance, we reject the null hypothesis if the p-value is less than or equal to 0.05, from the output, the test After Paragraph statistic is 0.935 while the p-value is 0.000 which is less than 0.05 therefore we reject the null hypothesis and conclude that there is sufficient evidence to prove that the data are not normally Bullets & Lists distributed.
