Could you please explain the answer. I trying to understand the process of answering this question.
Transcribed Image Text: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.

The chi square value of 37.724 is higher than the chi square value of 3.84; therefore, we do not reject Ho at 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.
