Question

This activity involves testing a hypothesis about a population mean, μμ We will test a hypothesis about the volumes of Coke, Diet Coke, Pepsi or Diet Pepsi. The claim by the manufacturers is that the average volume of soda is at least 12 ounces. Assume that the population standard deviation, σ,σ,is known to be 0.01 ounces.

1. Decide the significance level you are going to use to test.

2. Determine the mean (average) and the standard deviation of the volume of your soda.

3. Complete the calculations below and graph.

 

Step 1:     H0H0: μμ_________________                            

                  HαHα: μμ________________

(make sure you put in the appropriate symbols, values and labels)

 

Step 2: α=α=_________________

Step 3: Critical value(s):  za=za=_______________

Step 4: Graph, label and shade the critical regions and label the critical values.

 

                                      

 

Step 5: Test statistic (show all steps) : 
z=x′−μσn√=z=x′−μσn=

 

Calculate: mean:  _______________

standard deviation: ______________

variance: ____________________

z: ___________________________

 

Step 6: Decision criteria: reject H0 if  ztest ___________ zcv

Step 7: Decision _____________________

Step 8: Conclusion (write the appropriate conclusion with the claim):
