Question

1) The variability for impurities present in a batch of chemicals
used for a particular process depend on a length of a time that
the process in operation. Suppose a sample size is 25 drawn
from the normal process, which is to be compared to a new
sample of a new process that has been developed to reduce
the variability of impurities. L.O.S=0.05
n = =25, s? = 1.04,S2 = 0.51​

Answer 1

Step-by-step explanation:

1) The variability for impurities present in a batch of chemicals

used for a particular process depend on a length of a time that

the process in operation. Suppose a sample size is 25 drawn

from the normal process, which is to be compared to a new

sample of a new process that has been developed to reduce

the variability of impurities. L.O.S=0.05

n = =25, s? = 1.04,S2 = 0.51
