A researcher notes that there seems to be a difference in the prevalence of high blood pressure among college-educated individuals who consume low amounts of processed foods and the prevalence of individuals who only have a high school education and consume high amounts of processed foods. Use the appropriate hypothesis to test for the independence of the two independent variables presented here at the 5% significance level to ensure confounding has not influenced the study’s results. Then, interpret your response. please explain .

A) The chi square value of 158.652 is higher than the chi square value of 3.84; therefore, we do not reject H₀at the 5% level and reject H₁, which states that level of education and the amount of processed foods in an individual’s diet are not independent of one another.
B) The chi square value of 158.652 is higher than the chi square value of 3.84; therefore, we do not reject H₀at the 5% level and reject H₁, which states that level of education and the incidence of high blood pressure are not independent of one another.
C) The chi square value of 158.652 is higher than the chi square value of 3.84; therefore, we can reject H₀at the 5% level in favor of H₁, which states that level of education and the incidence of high blood pressure are not independent of one another.
D) The chi square value of 158.652 is higher than the chi square value of 3.84; therefore, we can reject H₀at the 5% level in favor of H₁, which states that level of education and the amount of processed foods in an individual’s diet are not independent of one another.
