The following data are measurements of body mass, in grams, of finches captured in mist nets 010during a survey of various habitats in Pakistan,

Crimson-rumped Waxbill:       8,         8,         8,         8,         8,         8,         8,         6,         7,                                                         7,         7,         8,         8,         8,         7,         7,         7.

Cutthroat finch:          16,       16,       16,       12,       16,       15,       15,       17,       15,       16,                                           15,       16.

White-browed sparrow weaver:          40,       43,       37,       38,       43,       33,       35,       37,

36,       42,       36,       36,       39,       37,       34,       41.

A)        Calculate the mean body mass of each of these three finch species. Which species is largest, and which is smallest? (Here and forever after, provide units with your answer.)

B)        Which species has the greatest standard deviation in body mass? Which has the least?

C)        Calculate the coefficient of variation (CV) in mass for each finch species. How different are the coefficients between the species? Compare the difference in CVs with the differences in standard deviation calculated in part (b).

D)        Given the following measurements of beak length, in mm, of the 16 white-browed sparrow weavers, which measurement is more variable in this species (relative to the mean), body mass or beak length?

10.6, 10.8, 10.9, 11.3, 10.9, 10.1, 10.7, 10.7,

10.9, 11.4, 10.8, 11.2, 10.7, 10.0, 10.1, 10.7

can anyone answer this question for me?
