A standard measurement of the problem solving ability of a mouse is the time that it takes to find the exit of a maze. Historically, the average time required for a mouse to find the exit is 18.0 seconds. You think that feeding the mouse Mr. Tom’s Magic Juice will make the mice find the exit faster. In order to test this hypothesis, you select 21 mice at random, feed them Mr. Tom’s Magic Juice, and let them run the maze. The sample mean is 15.6 seconds with a standard deviation of 2.4 seconds. A box plot of the maze run times is symmetrical with no outliers. c) Calculate the value of the test statistic for these data

Question
A standard measurement of the problem solving ability of a mouse is the time that it takes to find the
exit of a maze. Historically, the average time required for a mouse to find the exit is 18.0 seconds. You
think that feeding the mouse Mr. Tom’s Magic Juice will make the mice find the exit faster. In order to
test this hypothesis, you select 21 mice at random, feed them Mr. Tom’s Magic Juice, and let them run
the maze. The sample mean is 15.6 seconds with a standard deviation of 2.4 seconds. A box plot of the
maze run times is symmetrical with no outliers.
c) Calculate the value of the test statistic for these data
