[商管] [統計]-機率分配
A manufacturers’s quality control department is testing whether
the probability to have defective products is 2% or more
(i.e. H0: p=0.02 ; Ha: P>0.02).
The department randomly checks 100 products and records the number
of defective products (Y).
The decision rule to reject H0 is Y>2.
Use Poisson distribution to approximate the Type I error (α), which is :
a. 7exp(-2)
b. 1-7exp(-2)
c. 5exp(-2)
d. 1-5exp(-2)
e. None of above
