Question: Experiments on learning in animals sometimes measure how long it takes mice to find their way through a maze. The mean time is 18 seconds

Experiments on learning in animals sometimes measure how long it takes mice to find their 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.

The sample mean is x = 16.5 seconds. The null hypothesis for the significance test is

(a) H0: μ = 18.

(b) H0: μ = 16.5.

(c) H0: μ < 18.
