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?
SQL: SELECT SUM("yield_neutrons_per_fission") FROM delayed_neutron_data WHERE "decay_constant_s_1" < 0.301 AND "half_life_s" = 22.72 AND "group" > 2

Question: What is the decay constant with a half-life less than 22.72, a yield, neutrons per fission of 0.0031000000000000003, and a group number less than 3?
SQL: SELECT COUNT("decay_constant_s_1") FROM delayed_neutron_data WHERE "half_life_s" < 22.72 AND "yield_neutrons_per_fission" = 0.0031000000000000003 AND "group" < 3

Question: What is the lowest half-life with a yield, neutrons per fission bigger than 0.0031000000000000003 and a decay constant less than 0.030500000000000003?
SQL: SELECT MIN("half_life_s") FROM delayed_neutron_data WHERE "yield_neutrons_per_fission" > 0.0031000000000000003 AND "decay_constant_s_1" < 0.030500000000000003
