1. Following the explosion of the 25th space shuttle flight‚ which was caused by an O-ring failure in one or more of the booster rockets‚ data from the previous 24 flights were studied. The Temperature (F) at the time of launch and whether or not there was evidence of O-ring failures for each of the previous 24 shuttle flights was determined for each flight. A logistic regression relating the Failure of O-rings to the Temperature was obtained with the following result: Estimate Std. Error z value Intercept
