study looked at the effects of light on female mice. Fifty mice were randomly assigned to a regimen of 12 hours of light and 12 hours of dark (LD), while another fifty mice were assigned to 24 hours of light (LL). Researchers observed the mice for two years. Two of the LD mice and 16 of the LL mice developed tumours. (You may want to create a table to represent this data.)

Question

study looked at the effects of light on female mice. Fifty mice were randomly assigned to a regimen of 12 hours of light and 12 hours of dark  (LD), while another fifty mice were assigned to 24 hours of light  (LL). Researchers observed the mice for two years. Two of the LD mice and 16 of the LL mice developed tumours. (You may want to create a table to represent this data.)
