There is more variation in the times for restaurant A.
B) Restaurant A:

46 \mathrm { sec } ; 260.79 \mathrm { sec } ^ { 2 } ; 16.15 \mathrm { sec }

Restaurant B:

44 \mathrm { sec } ; ^ { 285 } .64 \mathrm { sec } ^ { 2 } ; 16.90 \mathrm { sec }

There is more variation in the times for restaurant
