The paper “Cigarette Tar Yields in Relation to Mortality from Lung Cancer in the Cancer Prevention Study II Prospective Cohort “ (British Medical Journal [2004]: 72-79) included the accompanying data on the tar level of cigarettes smoked for a sample of male smokers who subsequently died of lung cancer.

Assume it is reasonable to regard the sample as representative of male smokers who die of lung cancer. Is there convincing evidence that the proportion of male smoker long cancer death is not the same for the four given tar level categories?

EXPERIMENT ONE

On a standard test of attention span in children, Dr. Niederjohn wants to know whether attention span is different in children who play video games extensively.  He selects a sample of children who regularly play video games and those who do not and obtains the following attention-span data:

1. Give the M and SD for each group:

2. Using SPSS compute the appropriate test. Paste SPSS output here.

EXPERIMENT TWO

Dr. Marek wants to replicate the previous study. She selects a different sample of children who regularly play video games and those who do not and obtains the following attention-span data:

3. Give the Mand SDfor each group:

4. The difference between the means in experiment 1 is the same asthe difference between the means in experiment 2.

5. The variability in experiment 1 is less thanthe variability in experiment 2.

6a. Given your answer to numbers 4 and 5, the results of EXPERIMENT TWOare less likely

to be significant compared to the results of EXPERIMENT ONE?  

6b. Why? How will the numerator and denominator of the t-obtained formula be affected by the answers to questions 4 and 5? Note: you will be graded in part on the clarity of your answer. When you make comparisons between the two experiments, clearly identify which experiment you are referring to.

7. Using SPSS compute the appropriate test. Paste SPSS output here.

With alpha set at .05, write a conclusion of the findings.

Be sure to report the appropriate statistic in APA style.   

EXPERIMENT THREE

Dr. Ziegler wants to replicate the previous study once again.  She selects a different sample of children who regularly play video games and those who do not and obtains the following attention-span data:

You are the senior system administrator in your company and are known for your Active Directory expertise. Your specialty is Group Policy Objects (GPO) and tracking changes. Your boss tells everyone about a tool developed by Microsoft called “Policy Analyzer” for tracking changes and troubleshooting GPO. He would like you to conduct a “lunch and learn” about Policy Analyzer for your Windows Administration Team. You realize that the product’s name has been changed to “Microsoft Security Configuration Toolkit”. Diplomatically conduct the lunch and learn and discuss the history of the tool, the name change, the features of the product and the benefits to your Windows Administration team in managing GPO.

A minimum of two references is required one of which can be your textbook.

Provide a PARAGRAPH description of each of the three experiments below: 1.) Asch Conformity Experiment. 2.) Milgram Obedience Experiment. 3.) The Stanford Prison Experiment. ALL THREE HAVE TO BE ANSWERED TO EARN CREDIT.

What is the major advantage to constructing a paired difference experiment when comparing two population means?

a) The paired difference experiment accounts for dependence between data pairs.

b) The paired difference experiment benefits from the fact that selecting samples independently is always optimal

c) The test statistic is easier to calculate

d)The paired difference experiment guarantees a strong linear correlation

1. p, which is twice as long as v and points in the same direction as v
2. q, which has the same length as v and points in the opposite direction of v
3. r, which is three quarters the length of v and points in the same direction as v
