Read the following passage and see the figure below. This is question 2 of 2 about this passage and figure. “The popular herbicide atrazine induces a compound that converts testosterone into estrogen. Researchers wanted to know whether the survival of some amphibian species could be at risk due to atrazine’s effects on the number, function, and fertility of males. In Hayes et al. (2002), researchers tested the hypothesis that atrazine reduces testosterone levels in male frogs by exposing one group of 90 male frogs to 25 parts per billion (ppb) atrazine every 3 days for 46 days. A group of 90 control males and a group of 90 control females were treated identically to the atrazine-treated group, except they were not exposed to atrazine. All frogs were housed individually and fed Purina rabbit chow. After 46 days, individual testosterone levels were measured in frogs from each group. The results are below.” QUESTION: Identify the researchers’ hypothesis and prediction.

41. A physical therapist takes a PTA into a PT Evaluation. She wants to review their screening criteria to give the PTA a better example on how to create interventions. These are the highlights: (1) Patient complaints of hip stiffness, especially worse in the morning, but resolves by the time they walk to the bathroom. (2) Hip IR 30, and painful. (3) Hip Flexion is 90. Based on Altman’s Criteria make True if the patient is positive or false you believe if they are negative
