Number of Bird colonies: (57, 31, 25, 32, 33, 10, 18, 9, 12, 14,
10, 26, 4, 16, 13)
Altitudes at which this number of bird colonies was found:
(2397, 1264, 1170, 1060, 1900, 460, 1998, 700, 735, 613, 662, 1502,
750, 2275, 552)
QUESTION ONE: can we compare spread of altitude and number of
bird colonies?
QUESTION TWO: Is spread a unit free measure of variability?

Using the returns shown above, calculate the arithmetic average
returns, the variances, and the standard deviations for X and Y.
Fill in the table below. (Do not round intermediate
calculations. Enter your average return and standard deviation as a
percent rounded to 2 decimal places, e.g., 32.16, and round the
variance to 5 decimal places, e.g., .16161.)...
