The question: To investigate if there is evidence to suggest that the two operations brick and tile have a difference in accident rates. This type of question involves analysing the data for a difference‚ and so tests such as an equal variance test‚ a normality test and a Mann Whitney test will be undertaken. The meaning and the significance of these tests will be explained and justified later on in the report. Hypothesis Testing: The null hypothesis (Ho) for this investigation is that
