Can you explain if this data from this question represent a sample or a population? I think it is a sample but all the correct answers the teacher provided derive from using formulas like population variance and population standard deviation.
This data set is related to the explosion of the USA Space Shuttle Challenger on 28 January,
1986. Investigation into the reliability of the shuttle's propulsion system revealed the failure
of one of the three field joints on one of the two solid booster rockets. Each of these six
field joints includes two O-rings, designated as primary and secondary, which fail when
phenomena called erosion and blowby both occur (Draper, 1993). The file used below contains data that was collected from 23 previous flights as a part of Draper, (1993).
Given this data file, calculate the following items:
a. The mean,
b. The
c. The mean and standard error of the Launch Temperature
d. The standard error of the Leak-Check Pressure
