INEN314 Homework #10
(Due 11/21)
The following problems are related to your experiments in Lab#9.
You need to use the data collected
from the Lab to finish this homework.
1.
Use the data from Step 4, how do you construct a control chart for
an individual X control chart
,
i.e.,
n
=1. How will you determine
σ
ˆ for
n
=1? Do
NOT
need to revise your control limits even if
you find outofcontrol condition.
Same below
.
[4 pts]
2.
Construct the Xbar chart and R chart for
n
=2, 5, 10. For
n
=2, use two consecutive data as a sample.
The same logic applies to the cases with
n
=5 and
n
=10.
When
n
varies, the total number of samples,
i.e., the value of
m
, also varies.
Obviously
m
=80/
n
.
When
n
=2, 5, and 10,
m
will be 40, 16, and 8,
respectively.
[5 pts]
3.
Construct the Xbar and S chart for
n
=2, 5, 10, following the same way as you did in (2).
