Your answer is partially correct.
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):
83 48 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
Round your answers to 2 decimal places (e.g. 98.76).
(a) Using the entire data, calculate the sample mean and sample standard deviation.
Sample meani 65.26
Sample standard deviation =
(b) Remove the smallest observation (31°F) and calculate the sample mean and sample standard deviation of the remaining data.
Sample mean = i 66.23
11.02
Sample standard deviation - i 9.99
(c) With the smallest observation
removed:
the sample mean increased
and the sample standard deviation decreased
