(1) We would use one-sample hypothesis test when we want to test for a population parameter, whereas we use two-sample hypothesis test when we want to compare the two samples that may be drawn from a single or two different populations.

Consider the claim that the mean life of bulbs produced by a company is 1000 hours with a standard deviation of 10 hours.

If we want to test this claim, then we draw a sample of, say 50 bulbs and compute the z- value using the mean and standard ...
