Diet Low in Processed Foods Total Non-smoker Smoker Total 179 221 400 Normal Cholesterol High Cholesterol 124 55 69 152 193 207 Diet High in Processed Foods Normal Cholesterol High Cholesterol 64 85 98 153 162 238 Total Non-smoker Smoker Total 149 251 400 A researcher notes that there seems to be a difference in the prevalence of diabetics who smoke and consume diets high in processed food and the prevalence of diabetics 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. The chi-square value of 158.652 is higher than the chi-square value of 3.84, therefore we can accept HO at the 5% level and reject H1, which states that smoking status and the amount of processed foods in an individual's diet are not independent of one another. The chi-square value of 158.652 is higher than the chi-square value of 3.84, therefore we can accept HO at the 5% level and reject H1, which states that smoking status and the incidence of diabetes are not independent of one another. The chi-square value of 158.652 is higher than the chi-square value of 3.84, therefore we can reject HO at the 5% level in favor of H1, which states that smoking status and O the incidence of diabetes are not independent of one another. The chi-square value of 158.652 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.

Answer 1

From the chi square values it ie clear that the last option is correct.

As chi sq value is higher we reject the null hypothesis, and conclude there is no independent between variables.
