2 EWMA Control charts using Minitab as explained in the project description
Budget: $10 – $30 USD
simulate a data that follow Binomial distribution (20 samples) using minitab then simulate an out of control shift size of 4Po where Po=0.05 in both graphs.
EWMA graph 1 statistical parameters:
n = 50 λ = 0.2 h = 1 UCL = 3.796
EWMA graph 2 statistical parameters:
n = 16 λ = 0.455 h = 0.32 UCL = 2.557
we need the graphs to illustrate that the out of control in graph 2 happened/detected faster
