2. Consult the data below, showing weights of two species of African bird. (6 pts) a) Calculate the coefficient of variation (CV) for the weights of each bird species, and explain in words how to interpret these CV's. Crimson-rumped White-browed waxbill weights (g) sparrow-weaver weights (g) 40 43 DO D0 00 00 37 38 43 00 DO 33 35 37 36 42 36 36 39 37 34 41 (4 pts) b) Calculate a confidence interval for the white-browed sparrow-weaver weights (you can use the 2SE rule), and explain what a confidence interval means (as though you were explaining to a classmate)
