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