user: ### NOW ANSWER:
Question: What is the yield, neutrons per fission of the group with decay constants less than 0.301, a half-life of 22.72, and a group number larger than 2?
Columns: ['Group', 'Half-Life (s)', 'Decay Constant (s −1 )', 'Yield, Neutrons per Fission', 'Fraction']
Types: ['real', 'real', 'real', 'real', 'real']
Sample row: [1.0, 55.72, 0.0124, 0.00052, 0.000215]
SQL:

assistant: SELECT SUM("Yield, Neutrons per Fission") FROM "Table" WHERE "Decay Constant (s −1 )" < 0.301 AND "Half-Life (s)" = 22.72 AND "Group" > 2.0;
