Probability values (p) in bold are significant at a 5% significance level; CI = 95% confidence interval. Prediction Equations: Peanut Butter = 1/(1 + exp(−(0.01 + 0.53 × Age Young + 0.43 × Education Level Post High School))); Peanut Flour = 1/(1 + exp(−(−0.41 + 0.62 × Gender Female + 0.53 × Age Old + 0.53 × Education Level High School and Below))); Roasted Peanuts = 1/(1 + exp(−(0.09 + 0.76 × Gender Male + 0.39 × Occupation Full-time))); Boiled Peanuts = 1/(1 + exp(−(0.69 + 0.44 × Education Level Post High School + 0.72 × Monthly Income Medium and High))); Raw Peanuts = 1/(1 + exp(−(0.49 + 1.34 × Gender Male + 0.78 × Age Old + 1.10 × Education Level Post High school + 0.83 × Monthly Income Low))); Peanut Cooking Oil = 1/(1 + exp(−(−2.20 + 0.94 × Gender Male−0.490 × Age—old + 0.72 × Education Level High School and Below + 0.71 × Occupation Fulltime + 1.47 × Monthly Income Low))).
