Answer 1

Answer 13

Lean manufacturing is defined as the process in which the waste is removed from the manufacturing and making the manufacturing process more efficient.

Removing the waste from the manufacturing process also results in increased profit for the manufacturer.

So, only option B is correctly defining the lean manufacturing.

Option B is correct answer

Answer 14

Option A is correct because the scheduling function is used to assign and prioritise tasks in the project management based on their time completion. Scheduling function makes efficient use of all the equipment given for the task completion, thus we can say that it is a major tool for the management of projects.

Answer 15

We know that when we have population standard deviation, i.e. when the population standard deviation is known, we use z distribution and when the population standard deviation is unknown, we use t distribution.

So, option C is incorrect about the t distribution because when the population standard deviation is known, then we use z distribution and not t distribution for calculation of confidence interval.
