An experiment was conducted to compare three types of asphalt. Samples of each type of asphalt were subjected to repeated loads at high temperatures, and the resulting cracking was analyzed. For type A. 57 samples were tested, of which 9 had severe cracking. 17 had medium cracking, ami 3 I had minor cracking. For type B. 49 samples were tested, of which 4 had severe cracking. 9 had medium cracking, and 36 had minor cracking. For type C. 90 samples were tested, of which 15 had severe cracking. 19 hail medium cracking, and 50 had minor cracking. Does this experiment provide any evidence that the three types of asphalt are different with respect to cracking?
