Question

Different breeding lines of rats ran a maze, then were exposed to an EMP (electro magnetic pulse, such as would occur from a nuclear explosion then ran a similar maze again. The maze running times were compared and the rats were classified into 3 groups. After slower than before, after close to before, and after faster than before. The categories are shown in the table below. Are different broads reacting differently to radiation? Test at the .01 level.

Breeding line	Slow	Medium	Fast
1	20	15	10	45
2	24	15	25	64
3	15	15	1	45
4	25	15	25	75
5	12	11	5	28
6	6	20	8	34
	102	91	98	291

Answer 1

We conclude that different broads are not reacting differently to radiation
