The Report of the Presidential Commission on the Space Shuttle Challenger Accident in
1986 shows a plot of the calculated joint temperature in Fahrenheit and the number of O-
rings that had some thermal distress.You collect the data for the seven flights for which
thermal distress was identified before the fatal flight and produce the accompanying plot. (a)Do you see any relationship between the temperature and the number of O-ring failures?
If you fitted a linear regression line through these seven observations, do you think the
slope would be positive or negative? Significantly different from zero? Do you see any
problems other than the sample size in your procedure?
