Sample proportion = 
p difference = -0.00219
Assuming H0 to be true, std error of proportion
=
Test statistic Z = p diff/std error = -1.38641
p value = 0.0828
since p value >0.05 our significance level
we accept null hypothesis
There is no statistical evidence of a real drop in the contribution rate.
Thank you so much! merry christmas.
