Quality control personnel at a cookie factory are looking at the weights of boxes of cookies. The boxes are supposed to weigh 1 pound. They select every hundredth box of cookies and weight the contents. This procedure results in a sample that can be considered to be representative of the population of all boxes of cookies made at this factory on this day. The resulting net weights (pounds) of cookies comprise the sample of weights from 12 boxes:

1.038 1.012 1.008 1.004 0.997 0.998 1.012 0.997 1.004 0.999 1.000 1.006

Which hypotheses will the quality control people use? MORE THEN ONE ANSWER CHOOSE ALL THAT APPLY:

Ho: mu NE 1 versus Ha: mu = 1

Ho: mu GE 1 versus Ha: mu < 1

Ho: mu =1 (We don't need another hypothesis.)

Ha: mu NE 1 (We don't need another hypothesis.)

Ho: mu = 1 versus Ha: mu NE 1

Ho: mu LE 1 versus Ha: mu > 1
