Experiments on learning in animals sometimes measure how long it takes mice to find their way through a maze. The mean time is 1
8 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 alternative hypothesis for the significance test is ________.a. :μ≠18b. :μ=16.5.c. :μ<18.
Since its telling you that x is the number of years and the question is "How much does the cost of milk increase EVERY YEAR" then you can conclude that the cost is increasing by 0.25 each year
