Step-by-step explanation:
given that the Paralyzed Veterans of America recently sent letters to a random sample of 100,000 potential donors and received 4781 donations

(left tailed test)
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.
