determine the hypothesis: state the null and alternative hypothesis. write in context words first, then use symbols
(2pts)Experiments on learning in animals sometimes measure how long it takes a mouse to find its way through a maze. The mean time is 20 minutes for a particular maze. A researcher thinks that plying rap music will cause a mice to go through the maze slower. He measured the time of going through the maze of 12 mice as a sample. (2pts)The average footage of a one-bedroom apartment in a new student-housing development is advertised to be 880 square feet. A student group think that the apartments are smaller than advertised. They hire an engineer to measure a sample of apartments to prove their belief.Explanation / Answer
a) null hypothesis: mean time for a mice to go through the maze is equal to 20 minutes
alternative hypothesis: mean time for a mice to go through the maze is less than 20 minutes
H0: µ = 20
H1: µ < 20
b) null hypothesis: mean size of a one bedroom apartment is equal to 880 square feet
alternative hypothesis: mean size of a one bedroom apartment is less than 880 square feet
H0: µ = 880
H1: µ < 880
