Answer:
The correct option is C, the increase in productivity is 18.75%
Explanation:
The quantity before installing the new process=(100%-20%)*300
That is 80% of 300units=240units
The quantity after installation is (100%-5%)*300
That is 95% of 300=285units
The increase is 45units(285-240)
Hence % increase =45/240*100=18.75%
That is 18.75% increase in production output due to the installation of the new process
Answer: See explanation
Explanation:
The null hypotheses for the above scenario will be the statement of no effect and it'll be the mean weight of the bag that filled will be 420 grams.
H0: μ = 420
The alternative hypotheses for the above scenario will be that the bag isn't filled with 420 grams. They are either underfilled below 420 grams or overfilled above 420 grams.
Ha: μ ≠ 420
