QUESTION:
Construct normal probability plots of the cold start ignition time data presented in Exercises 6-69 and 6-80. Construct a separate plot for each gasoline formulation, but arrange the plots on the same axes. What tentative conclusions can you draw?
ANSWER:Solution:
Step 1 of 2:
We have two data sets one is “cold start ignition time” of an automobile engine is being investigated by a gasoline manufacturer.
1.75 |
1.92 |
2.62 |
2.35 |
3.09 |
3.15 |
2.53 |
1.91 |
Then we have the data of cold start ignition time of a particular gasoline used in a test vehicle.
1.83 |
1.99 |
3.13 |
3.29 |
2.65 |
2.87 |
3.4 |
2.46 |
1.89 |
3.35 |
The claim is to construct separate Normal probability plot.
