A bag of potato chips is packaged by weight.A total of 36 bags are purchased, and weighed
Question:
A bag of potato chips is packaged by weight.A total of 36bagsare purchased, and weighed and the mean weight of these 36bagsis 10.75ounces.Suppose that the standard deviation of the population of all such bags of chips is 0.6ounces.The stated weight on all packages is 11ounces.Set alevel of significance at 0.01.Is this hypothesis rejected or accepted? Note: Please do not forget to consider the following main points for testing your Null Hypothesis as required: State your Null Hypothesis and Alternative Hypothesis: show Alpha (level of significance) and confidence level (1 - alpha) if required; select your test statistic (Z, t, or Chi-square); set up critical value(s) based on the level of significance and/or degrees of freedom; collect data and compute the test statistic (i.e., what does Z, t, or Chi-square equal to); make a statistical decision (based on comparing critical value with the calculated test statistic and/or with respect to its relevant p-value) to either Reject or FTR=fail to reject the Null Hypothesis (H0); and express your decision and conclusion statement to finalize your answer to the problem at hand based on the specific test you used.
