720 658 737 837 731 1046 926 471 763
a)
Plot the histogram and frequency histogram dividing the data into six equal
class intervals of equal length (109 mm).
Plot the cumulative frequency distributions.
Estimate the parameters for the central value of the annual precipitation.
b)
Estimate the parameters representing the dispersion of the data.
Compute the skewness coefficient. Can the data be considered to be symmetrical?
