Experiments on learning in animals sometimes measure how long it takes mice to find their way through a maze. The mean time is 1
8 seconds for one particular maze. A researcher thinks that a loud noise will cause the mice to complete the maze faster. She measures how long each of 10 mice takes with a noise as stimulus. The sample mean is x = 16.5 seconds.The alternative hypothesis for the significance test is ________.a. :μ≠18b. :μ=16.5.c. :μ<18.
