Question
The following data are the joint 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 a) Find the median and the upper and lower quartiles of temperature. b) Set aside the lowest observation (31°F) and recompute the quantities in part (a). Comment on your findings. How "different" are the other temperatures from this lowest value? c) Construct a box plot of the data and comment on the possible presence of outliers.Explanation / Answer
