A production process for the JMF Semicon is monitored. Ten (10) samples of n = 15 observations have been collected with the following results:

Sample	Mean	Range
1	251	29
2	258	45
3	233	36
4	275	25
5	234	35
6	289	20
7	256	3
8	265	19
9	246	14
10	323	46

a. Develop the appropriate control chart and complete the means and the range charts.
b. Is the process under control? Explain.
