There are many claims that eating organic food leads to better health outcomes. To study this, a dietician collects data from her patients: She categorizes their blood pressure values into elevated and healthy and she administers a questionnaire from which she is able to classify their diet into high in organic food and low in organic food. The number of patients with high organic food consumption who had elevated and healthy blood pressures were 33 and 74 respectively. The number of patients with low organic food consumption who had elevated and healthy blood pressures were 287 and 395 respectively.
Determine whether there appears to be a statistically significant relationship between type of diet and blood pressure, she would conduct a χ2 analysis. Based on the results of her analysis, which of the following is the most appropriate conclusion?
Group of answer choices
Eating higher amounts of organic food appears to significantly reduce the risk of high blood pressure (P > 0.05).
Eating higher amounts of organic food appears to significantly reduce the risk of high blood pressure (P < 0.05).
Eating higher amounts of organic food appears to significantly elevate the risk of high blood pressure (P < 0.05). These data do not provide sufficient evidence that eating higher amounts of organic food changes the risk of high blood pressure (P > 0.05).
