A machine that fills shipping containers with driveway filler
mix is set to deliver a mean fill weight of 70.0 pounds. The
standard deviation of fill weights delivered by the machine is
known to be 1.0 pounds. For a recent sample of 35 containers, the
fill weights are listed in data file Quiz 1, located in the
"Homework Quiz Data Sets" module. Using the mean for this sample,
and assuming that the population standard deviation has remained
unchanged at 1.0 pounds, examine whether the mean fill weight
delivered by the machine might now be something other than 70.0
pounds. Using the 0.05 level of significance, what conclusion will
be reached?
I.DETERMINE AND STATE THE NULL HYPOTHESIS (HO) & THE
ALTERNATIVE HYPOTHESIS (H1).
II.STATE THE LEVEL OF SIGNIFICANCE, α.
III. DETERMINE THE SAMPLING DISTRIBUTION OF THE APPROPRIATE
STATISTIC AND STATE THE TEST STATISTIC.
IV. DETERMINE & STATE THE DECISION RULE.V.CALCULATE THE
VALUE OF THE TEST STATISTIC.
VI. MAKE THE DECISION – STATING THE LEVEL OF SIGNIFICANCE.
VII. DRAW THE CONCLUSION:1. IN REGARD TO THE ORIGINAL PROBLEM
STATEMENT.2. ALWAYS IN TERMS OF THE ALTERNATIVE HYPOTHESIS (H1).3.
IF THE DECISION WAS TO REJECT HO, A STRONG CONCLUSION CAN BE MADE.
4. IF THE DECISION WAS TO FAIL TO REJECT HO, A WEAK CONCLUSION MUST
BE MADE.
