Experiments are done to find out how long it takes rabbits to find their path through a maze. Mean time u=18 seconds is completion time for a maze. A scientist suggests that carrots will cause the rabbits to complete the maze faster. Experiments are done on 4 rabbits with carrots as a stimulus and the time in seconds are recorded 15,15,16,17

1.State the ho and ha

2.assume that the distribution of times is normal, do these experiment results support the scientists claim at significance level of a=0.05

Solutions

Expert Solution

claim : Ha : sample mean < 18

H0 : sample mean >= 18

mean = 15.75

yes,

experiment results support the scientists claim at significance level of a=0.05
