Answer: 10.28

Step-by-step explanation:

For the binomial distribution ,

standard deviation : [tex]\sigma=\sqrt{p(1-p)n}[/tex], where p = population proportion, n = sample size.

Given:  n= 503 and p=0.7

Then, [tex]\sigma=\sqrt{503\times0.7(1-0.7)}=\sqrt{105.63}\approx10.28[/tex]

Hence, the  standard​ deviation = 10.28
