Consumer’s general knowledge about organic food and olive oils is low (Table 2), since the confidence interval
of the mean (2.720, 3.007), with a level of significance of 99.9%, includes the scale average. In line with these
results, the expected score given the hypothesis of random response was 3, almost 70% of respondents answered
fewer than 4 questions correctly, and 86.5% of the sample is an olive oil or organic food consumer.
