She took a random sample of 225225225 people from her city and found that 363636 of them were senior citizens. She wants to test H_0:p=0.10H 0 :p=0.10H, start subscript, 0, end subscript, colon, p, equals, 0, point, 10 versus H_\text{a}:p > 0.10H a :p>0.10H, start subscript, start text, a, end text, end subscript, colon, p, is greater than, 0, point, 10, where ppp is the proportion of people in her city that are senior citizens. Assuming that the conditions for inference have been met, calculate the test statistic for Ellie's significance test. You may round to two decimal places.
