To study learned behavior in mice, researchers used a sample of mice in a maze experiment. Each mouse had to find its way through a maze to reach food at the end. The mouse was timed on its first rus through the maze and again on its tenth run through the maze. The difference in the times was recorded for each mouse.
Which of the following is the most appropriate inference procedure for the researchers to use?
a. A two-sample z -interval for a difference between proportions
b. A two-sample f -interval for a difference between means
c. A matched-pairs f-interval for a mean difference
d. A one-sample z-interval for a population proportion
e. A one-sample t-interval for a sample mean difference
