Question

1 point) The common fruit fly Drosophila melanogaster is the most studied organism in genetic research because it is small, easy to grow, and reproduces rapidly. The length of the thorax (where the wings and legs attach) in a population of male fruit fies is approximately Normal with mean 0.800 millimeters (mm) and standard deviation 0.078 mm. Note: Use Table A to find the proportion below (a) What proportion of flies have thorax length 0.83 mm or longer? (b) What proportion have thorax length between 0.83 mm and 0.965 mm?

Answer 1

The required proportion or probability can be directly calculated against the given length . First we need to covert the given length into z score and the probability can be directly obtained from z table or Excel or using any other software .
