A biologist is studying the effect of exposure to radiation in mice. She hypothesizes that the rate of cancer will increase after exposure. 30 mice of the same age were irradiated. Generally,one out of every 10 mice that age has cancer. Out of the thirty mice exposed, 7 of them were found to have cancer. Test at the 0.05 level. (i) What are the null and alternative hypotheses? (ii) What is alpha and the p-value? (iii) What conclusion do we make after performing this test?
