Eight samples gathered with the following results: Sample 1 N34607 00 2 5 8 Mean 4.2 4.4 3.6 3.8 4.9 3.0 4.2 3.2 343 Range 43 52 3 20 26 2 35 42 53 .36 42 R bservations have been 3.94 2.1 a. Using the data in the table, compute the center line, the upper control limit, and the lower control limit for the x and R charts. b. Is the process in control? Interpret the charts. c. If the next sample results in the following values (2.5, 5.5, 4.6, 3.2, 4.6, 3.2, 4.0, 4.0, 3.6, 4.2), will the process be in control?
