MINITAB CODE for Modern Engineering Statistics

(1) P. 12 Lag plot commands

Such a plot can be produced in MINITAB with the following sequence of commands.

MTB>LAG C1 C2 MTB>PLOT C1*C2

(2) P. 13 (Figure 1.5)

Code to produce Figure 1.5: MTB >SET C10 DATA> 1:49. DATA>END MTB>SET C1 DATA> ........ DATA>SET C2 DATA> .... .... DATA>END MTB>SORT C1 C2 C11 C12; SUBC>BY C1; SUBC>DESCENDING C1. MTB>PLOT C11*C12; SUBC>SYMBOL; SUBC>LABEL C10.

(3) P. 17 Histogram commands

With the data in the first column, the histogram was produced with the following MINITAB commands. MTB>HIST C1; SUBC>NINT 6.

(4) P. 19 (Figure 1.10) and P. 20 (Figure 1.11)

The first histogram was constructed using the following sequence of MINITAB commands: MTB>HIST C5; SUBC>FREQ; SUBC>CUTP 0 10 30 40. and the second histogram was constructed using MTB>HIST C5; SUBC>DENS; SUBC>CUTP 0 10 30 40.

(5) P. 21 (Figure 1.12) The plot was produced in MINITAB with the command BOXP.

(6) P. 23 (Figure 1.13) The chart was produced by using the MINITAB command PARETO. Specifically, by using

MTB>PARETO C2; SUBC>COUNTS C3.

(7) P. 97 The sequence of MINITAB commands alluded to at the end of Section 3.4.3.1 is the following. MTB>CDF 0.65 k1; SUBC>NORMAL 0.625 0.01. MTB>LET k2 = 1−k1 MTB>PRINT k2

(8) P. 146 (Example 5.2)

Assuming that the 25 observations are in the first column in MINITAB, this 99% confidence interval could be produced with the following commands
