researcher notes that there seems to be a difference in the prevalence of high cholesterol among individuals who smoke and consume diets high in processed food and the prevalence of high cholesterol among individuals who do not smoke and do not consume diets high in processed foods. Use the appropriate hypothesis to test for independence of two independent variables presented here at the 5% significance level to ensure confounding has not influenced the study's results. Then interpret your response. A. The chi square value of 37.724 is higher than the chi square value of 3.84, therefore we can accept H0 at the 5% level and reject H1, which states that smoking status and the incidence of high cholesterol are not independent of one another B. The chi square value of 37.724 is higher than the chi square value of 3.84, therefore we can reject H0 at the 5% level in favor of H1, which states that smoking status and the incidence of high cholesterol are not independent of one another. C. The chi square value of 37.724 is higher than the chi square value of 3.84, therefore we can reject H0 at the 5% level in favor of H1, which states that smoking status and the amount of processed foods in an individual's diet are not independent of one another.

researcher notes that there seems to be a difference in the prevalence of high cholesterol among individuals who smoke and consume diets high in processed food and the prevalence of high cholesterol among individuals who do not smoke and do not consume diets high in processed foods. Use the appropriate hypothesis to test for independence of two independent variables presented here at the 5% significance level to ensure confounding has not influenced the study's results. Then interpret your response.

	A.	The chi square value of 37.724 is higher than the chi square value of 3.84, therefore we can accept H₀ at the 5% level and reject H_1, which states that smoking status and the incidence of high cholesterol are not independent of one another
	B.	The chi square value of 37.724 is higher than the chi square value of 3.84, therefore we can reject H₀ at the 5% level in favor of H_1, which states that smoking status and the incidence of high cholesterol are not independent of one another.
	C.	The chi square value of 37.724 is higher than the chi square value of 3.84, therefore we can reject H₀ at the 5% level in favor of H_1, which states that smoking status and the amount of processed foods in an individual's diet are not independent of one another.
	D.	The chi square value of 37.724 is higher than the chi square value of 3.84, therefore we can accept H₀ at the 5% level and reject H_1, which states that smoking status and the amount of processed foods in an individual's diet are not independent of one another.
