A textile engineer is interested in measuring heat resistance for four different types of threads used in making fire-resistant clothing for firefighters. A random sample of 20 threads from each type was taken and subjected to hear test to determine resistance (the length of time the fibers survive before starting to burn). Explain what type of study this is and why.
