HW Assignment 1: Descriptive Statistics and Measurement Error
1.
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
HW 1 Data set_Challenger ORings.xlsx
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, median, and mode of the Leak-Check Pressure
b.
The range, variance, and standard deviation of the Launch Temperatures
c.
The mean and standard error of the Launch Temperature
d.
The standard error of the Leak-Check Pressure
Note: Complete work must be shown for points.
