Find the center line and control limits for each of the following situations.
a.* chart, sample size n = 6, X = 56.31,  = 4.16, no standard given.
b. chart, sample size n = 6, X = 56.31, = 4.16, no standard given.
c. chart, sample size n = 3, X = 182.3, = 29.4, no standard given.
d. chart, sample size n = 3, X = 182.3, = 29.4, no standard given.
e. chart, sample size n = 5, X = 182.3, = 13.8, standards are μ0 = 100.0 and σ0 = 5.0.
f. chart, sample size n = 5, X = 182.3, = 13.8, standards are μ0 = 100.0 and σ0 = 5.0.
g. chart, sample size n = 8, standards are μ0 = 2.500 and σ0 = 0.010.
h. chart, sample size n = 8, standards are μ0 = 2.500 and σ0 = 0.010.
