For numbers 2-7: Sea lice is a common parasite found among saltwater fish. Presence of the pests are said to be related to pollution in the bodies of water. A total of 50 random sample of fish from a certain bay was obtained. Each fish was analyzed whether an internal parasite (Y=1) was observed or not. Likewise, the amount of estrogenic compounds in the fish blood (X1, ppt) and the sex of the fish (X2, Male=1 and Female=0), using Female as base category, were recorded. Regression analysis was done and the model is given by (attached image): Based on the model, the odds of observing an internal parasite over not observing is _____ for male relative to a female fish, holding amount of estrogenic compounds constant. A. lower by 1.51 B. higher by 1.51 C. lower by e^1.51 D. higher by e^1.51
