Problem 19E
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) Compute the sample mean and sample standard deviation and construct a dot diagram of the temperature data.
(b) Set aside the smallest observation (31 oF) and recompute the quantities in part (a). Comment on your findings. How “different” are the other temperatures from this last value?

ANSWER:
Solution:
Step 1 of 3:
Here, the given data is the data of joint temperatures of O-rings of test firing or actual launch of space shuttle rocket.
The data is 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.
Using this we need to find the required values.
