QUESTION 8 Experiments on learning in animals sometimes measure how long it takes mice to find their way through a maze. Over the years, the mean time for completing a particular maze has been found to be 18 seconds with a sample standard deviation of s=2 seconds. A researcher thinks playing loud music will cause the mice to complete the maze in less time. She uses a sample of n=30 mice and has them complete the maze while playing a rock song at 100 decibels. The sample mean was found to be 17.5 seconds. At a 95% level of confidence, determine the researcher's conclusion resulting from this experiment. O At a 95% level of confidence, there is SUFFICIENT evidence to show the mice will complete the maze in less time. O At a 95% level of confidence, there is INSUFFICIENT evidence to show the mice will complete the maze in less time. The results are inconclusive Since there is sufficient evidence, we reject Ho.
