A research wants to determine if pre-natal exposure to the hormones in birth control pills alters the sex makeup of midshipman fish populations (which are typically half male and half female). Specifically, the researcher wishes to test the hypothesis that exposure to hormones will increase the number of females in the population. The researcher exposes a group of pregnant midshipman fish to birth control hormones and records the sex of the first 19 offspring birthed. They then observe that 16 are female. Use a sign test and a alpha of .05 to test the indicated hypothesis.
