The option is b

Step-by-step explanation:

From the question we are told that

The sample size is n = 2500

The number with a graduate degree is k = 555

The sample proportion is $\^ p = 0.222$

Generally the standard error is mathematically represented as

$SE = \sqrt{\frac{\^ p (1- \^ p )}{n} }$

=> $SE = \sqrt{\frac{0.222 (1- 0.22 )}{2500 } }$

=> SE = 0.010

Converting to percentage

SE = 0.010 * 100

=> $SE =10\%$
