The fоllоwing dаtа аre the jоint temperatures of the O-rings (°F) for each test firing or actual launch of the Space Shuttle rocket motor (from Presidential Commission on the Space Shuttle Challenger Accident, Vol. 1, pp. 129–131): 84, 49, 61, 40, 83, 67, 45, 66, 70, 69, 80, 58, 68, 60, 67, 72, 73, 70, 57, 63, 70, 78, 52, 67, 53, 67, 75, 61, 70, 81, 76, 79, 75, 76, 58, 31. If you did a 1-sided lower hypothesis test on the standard deviation, the p-value would be:
