(a)Forewing length is the average measurement for 10 bees, in mm;Femur length is the average measurement for 10 bees, in mm;

Fresh weight is the average weight for three groups of 10 bees each, in grams;

Dry weight is the average weight for three groups of 10 bees each, in grams.

 
(b)The probability a sample is European (PE) = 1-PA.
