A scientist wаnts tо study the effects оf sleep deprivаtiоn on test scores. She tаkes two groups of 25 students and asks them to watch the same lecture then take the same test the following day. One group of students is required to get at least 7 hours of sleep, the other group is required to get no more than 2 hours of sleep. She will then compare the test scores of the two groups. A) What are the independent and dependent variables of this experiment? (2 points) B) What is the null hypothesis for this experiment? (2 points) C) If the scientist finds that the sleep deprived students do worse on the exam would she reject or fail to reject the null hypothesis? (1 point) D) List 2 control variables (2 points) E) List 2 potential confounding variables for this experiment (2 points) F) Provide one way to mitigate either of the confounding variables you listed. (1 point)
