For the data appearing in, develop the T2 chart (I recommend letting Minitab do all the calculations for this chart) and comment on the stability of the process. If there is one (or more) point(s) out of control, try to determine if this is also indicated on the Xbar/R chart for one of the variates

	Variate 1	Variate 2
Subgroup	x1	x2	x3	x1	x2	x3
1	70.22	63.46	61.46	37.42	34.03	36.07
2	49.28	53.18	60.84	32.84	25.16	34.62
3	35.77	78.90	71.68	23.94	44.33	41.17
4	34.59	63.92	80.37	10.95	41.00	54.83
5	66.49	89.77	52.48	33.37	44.39	33.56
6	77.86	64.09	42.61	38.75	44.32	29.61
7	49.27	58.83	63.48	29.83	30.36	28.51
8	61.07	50.83	54.46	41.60	25.02	31.84
9	63.70	51.56	73.18	34.33	35.03	49.22
10	36.46	80.09	61.67	17.35	43.67	39.13

For Variate-1

Variate-2:

Xbar/R chart for each variable of variate-1

For the data appearing in, develop the T2 chart (I recommend letting Minitab do all the calculations for this chart) and comment on the stability of the process
