The size of adult green sea turtles in a population varies from turtle to turtle. Over 10 years the distribution of body sizes in the population has changed (see Figure above). Mathematically, how has the new turtle population changed relative to the original population? A The mean has stayed the same but the standard deviation has increased. B) The mean has increased but the standard deviation has stayed the same. None of these correct D all answers correct E The mean has stayed the same but the standard deviation has decreased. FThe mean has decreased and the standard deviation has decreased.
