Chapter 15, Problem 170E

(choose chapter or problem)

Consider the influenza data in Exercise 15-84. Use $\mu=160 \text { and } \sigma=2$

(a) Construct an EWMA control chart with $\lambda=0.1$. Use $L=2.81$. Does the process appear to be in control?

(b) Construct an EWMA control chart with $\lambda=0.5$. Use $L=3.07$. Compare your results to those in part (a).

Equation Transcription:

$\mu{}=160\ and\ \sigma{}=2$

$\lambda{}=0.1$

$L=2.81$

$\lambda{}=0.5$

$L=3.07$
