In an experiment to determine whether there is a systematic difference between the weights obtained with two different mass balances, six specimens were weighed, in grams, on each balance. The following data were obtained:



State the null and alternate hypotheses.

Select one:

A. H0: d > 0, H1: d < 0

B. H0: d = 0, H1: d < 0

C. H0: d = 0, H1: d = 0.01

D. H0: d = 0, H1: d 0

Solution

Ans is D.

Null hypothesis: H0: d = 0,

Alternative hypothesis: H1: d 0
