Answer:
Test statistic,
(to 3 dp)
Step-by-step explanation:
Deviation, d = x -y
Sample mean for the deviation


Standard deviation: 


SD =2.93
Under the null hypothesis, the formula for the test statistics will be given by:


We need to solve the speed formula for d. To do so, let's start by moving the number of the left hand side:

Square both sides to get rid of the square root:

Now plug the known value of the speed to find the distance:

So the closest answer is the last one: d=0.155km
36/4=9 48/3=16 so 9*16=144/2=72 so it is 72 square inches
