The assumptions hence are very important . If wrong assumptions are made or the assumptions made for the test are not met , then wrong and misleading conclusions might be made from a test , which may lead to not achieving the required objectives

The histogram displaying data for day one shows that the data follows a perfect normal distribution . The P-P plot also shows that the data actually follows a normal distribution and is portrays no form of significant skewness
The histogram for day two data shows that the data is not actually normally distributed since it has a significant skewness . The P-P plot supports this perspective by showing that there is presence of...
