The confidence interval concerns the distribution of sampleIs the following statement true or false: "The interval means that 2.5 % of tunafish are expected to have dosage less than 5.03 Bq/kg."meanswhich were repeatedly drawn from the same population.

Unfortunately, confidence intervals are nearly worth nothing (IMHO). All you can do with them is to state that you had a 95% a priori chance to catch the population mean with the 95% confidence iterval you wanted to construct.

With kind regards
