Prof. Richard Feynman was a member of the commission formed to determine the cause of explosion of the space shuttle, Challenger in 1986. He suspected that the low temperature of take-off caused the O rings to fail. He published the data on temperature versus the number of 0-ring incidents in 24 previous space shuttle flights. These data are tabulated below. O-ring incidents Temperature (Fahrenheit) 66 67 67 67 68 68 70 70 72 73 75 76 76 78 79 80 81 1 57 58 63 70 70 2 75 3 53 Investigate the hypothesis that the temperatures in the four samples are not coming from the same underlying population distribution; but that these populations differ somewhere. Obtain the value of the test statistic that is best applied to answer this question.
