A researcher reports that when groups of four children are randomly selected from a population of couples meeting certain criteria, the probability distribution for the number of girls is as given in the table below:

Number of Girls X	P(X)
0	0.502
1	0.365
2	0.098
3	0.034
4	0.001
Total	1.000

What is the standard deviation for the number of girls for this distribution? Round your answer to one place value more than the given data and attach units.

(Hint: The values of X are 0 girls, 1 girl, 2 girls, 3 girls, and 4 girls.)
