Following a study on the management style of business owners and the dominant development strategy, carried out on a sample of 115 American business leaders, your mandate is to verify if there is a link between these two variables.

strategy development	Leadership style		Total
	Artisan	Opportunistic
Specialization	Fobs = 26	Fobs = 38	64
Diversification	Fobs = 17	Fobs = 38	51
Total	43	72	115

Legend: Fobs = observed frequencies Knowing that n = 115, and that the significance threshold is set at 0.05 one-sided and that the application conditions are met, you must take the appropriate steps to check if the owner's management style is independent of the development strategy. Justify your answer and clearly show all the steps of your test
