6. A researcher is interested in the effect of amphetamine on water consumption. The researcher had eight rats and randomly chose four rats to inject with amphetamine and injected the remaining four with saline to use as controls. She measured the amount of water consumed by each rat over a period of 24 hours. The results in ml/kg is as follows: Amphetamine (group 1) Control (group 2) 119 124 125 165 168 182 104 157 mean - 129 mean = 157 sd = 27.46 sd - 24.34 Prior to the experiment, the researcher does not know if amphetamine will increase or decrease water consumption and is interested if the drug makes a difference. What are the appropriate hypotheses for this test? ? OH : y - y2 = 0 HA - 320 O H:-H2 = 0 HA:M-12 0 OH = 0 HA: -y
- 320 O H:-H2 = 0 HA:M-12 0 OH = 0 HA: -y
