avoidance reaction times (in milliseconds) on four tests. Two tests were done during the day in
daylight and two tests were done at night with reduced lighting.

This question has multiple parts. Create output to MATLAB's command window exactly as shown,
except replacing xxxx with actual values, as instructed. You may use the disp command, but not the
fprintf command
If you have difficulty with the alignment or formatting of numeric output, add the command format
shortg near the top of your solution.
In your solution, put the following MATLAB statements at the beginning of each part:
% Question 5<x> solution
disp('----- q5<x> solution -----');
Instead of "<x>", substitute the question part ("a" for part a, "b" for part b, and so on).
