It comprises with having effective control over creating thehypothesis that will be effective in meeting the sampling distribution level and analysing thehypothesis outcomes of the analysed data set. Moreover, to address the effective outcomes fromthe analysed data set which insist that there will be appropriate gains and losses. Therefore, toanalyse the data set there have been implication of various techniques which will be effective asper analysing relation between type of seeds as well as their colours. Thus, there will bepreparation of Two hypothesis such as:Null Hypothesis (H0): There is no significance difference in between colours of seedsand types of seeds.Alternative hypothesis (H1): There is a Significance difference between colours ofseeds and types of seeds.
