Answer :
Given data :
Variable
= 0.3
= 0.1
We have to first take mean of both the data values of time before and after rearrangement.
By which we can find the value of
where total number of outcome = 12
which will help in finding P-value and others.
I am attaching handwritten notes for step by step solution.
Please go through them :
Thanks

The time delay is measured for a city street. Variability in this value is estimated as o= 0.3 (for time in minutes) by experience. Traffic signs and lights were recently altered to facilitate traffic and reduce delays. Delay times in minutes for a random car sample before and after the rearrangement are shown below.
