, where p = proportion of success.
n= sample size.
As per given , we have
p=0.58
n= 500
Then, the standard deviation of the sample proportion in this situation would be :

Hence, the standard deviation of the sample proportion in this situation is 0.0221 .
There would be a a row of seven and would be 9 in each row
