Is this question simply a case of taking the Z-Score as 1.7 and reading off the table which I believe gives the answer of 0.446?
2) Species A of an animal weighs average of 50 pounds and has standard deviation of 3.3.
Species B average is 57.5 with standard deviation of 1.7.
A zoo has a species A weighing 45 pounds and B at 54 pounds. Explaining fully determine which is more underweight.
Could someone please direct me as to how i would go about finding this answer please.
