Question 1.

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 the 10 mice takes with a noise as stimulus. The sample mean is 16.5 seconds.

a) Construct the null and the appropriate hypothesis for the researcher, perform the statistical test for the researcher.

b) The assistant researcher decided to test the null hypothesis against the alternative

What would be the conclusion of his test?
