A 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 determine if diet and smoking status are related (independent) at the 5%. Determine the chi-square values and interpret your response.   Diet Low in Processed Foods Normal Cholesterol High Cholesterol Total Non-smoker 124 55 179 Smoker 69 152 221 Total 193 207 400   Diet High in Processed Foods Normal Cholesterol High Cholesterol Total Non-smoker 64 85 149 Smoker 98 153 251 Total 162 238 400
