Question

In the type of experiment in which failed items are immediately replaced, there is a tendency for shorter lifetimes to be observed more frequently than longer lifetimes. Is this a serious problem? Why or why not?

Answer 1

Yes, this is a serious problem to observe shorter lifetimes frequently than longer lifetimes because this will result in an overall loss of time and money in production. If failed items can be replaced then the experimenter is not likely to worry about the quantity of failed items as they can be replaced but as the quantity of failed will increase the amount of money and time required in producing item will increase.
