a) Determine the mean production of acorn in the last six years.
b) Calculate the standard deviation of data relative to acorn production.
c) Design the dispersion diagram and explain if we can conclude something about the relation between the annual production of acorn and the mean weight of pigs created in that farm property. Explain.
d) Calculate the correlation coefficient and explain it.
