Experiments on learning in animals sometimes measure how long it takes a mouse to find its way through a maze. The mean time is 18 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. Choose the correct null hypothesis H0 and alternative hypothesis Ha from the choices below. a) H0: µ = 18; Ha: µ 18. c) H0: y = 18; Ha: y 18. e) H0: µ = y; Ha: µ < y. f) H0: y = 18; Ha: y? 18. g) H0: µ = 18; Ha: µ? 18.
