After inspection, it was found that for process A there are 10 defective products and 30 good ones, while for process B there are 25 defectives and 60 good ones. Is the performance of the two processes significantly different?
Select one:
a. NO
b. YES
c. CAN'T SAY
d. NEITHER TRUE NOR FALSE
Answer c. Can't say.
The confidence with which we can say that the performance of the two processes significantly different depends on three factors
i. Sample size
ii. Percentage
iii. Population size
Since we do not know the population size we cannot say with confidence performance of the two processes significantly different.
