A physiological psychologist has performed an experiment to determine if a particular drug, smartozine, affects maze learning in rats. Three groups of 8 rats each are injected with one of three different doses of smartorine, while a fourth group of 6 rats is injected with a saline solution as a control. After the injection, rats in all four groups are timed in how long it takes them to learn to traverse a maze. The results of the experiment are presented below. Did smartozine affect how quickly the rats learned the maze. Use a level of significance of .05 SSB - 610 SSW - 1742 Match the hypothesis with the correct statement Premise Response Drag and drop to match Null Hypothesis = A The mean number of errors is greater than 100 2 Alternative Hypothesis The mean number of errors is not different from 100 At least one difference exists among the groups.
