Use the Excel file titled, General-Electric that is posted on GAP in the DataFile folder under the Supplementary Course Material section and upload it into SPSS. Complete the following tasks and copy your results in a word document and submit your report.

and upload it to SPSS. This file contains GE’s daily stock market data covering the period of 12/13/2010 to 12/11/2018. The file contains a total of 2013 daily transaction records including date, opening price of the GE stock for the day, highest price, lowest price, closing price, closing price adjusted for dividends, and the number of stocks traded (volume).

Use the explore command in SPSS and explain whether the trading volume of the stock is normally distributed. Make sure to discuss, Skewness, kurtosis, results from the test of normality as well as the Q-Q plots.

Select a random Sample of exactly 125 observations. Then run the descriptive command and calculate the mean and standard deviation of the sample. Repeat this process (i.e., selection of a random sample and descriptive command) exactly 75 times. Hint: Use SPSS syntax to repeat the command. List both values (mean and the standard deviation) in a new excel file with proper column headings.

Upload the newly created excel file into SPSS and create a histogram of both the calculated means and standard deviations.

Run the explore command similar to what you did in step 1 for both variables and make your observations. Does the Central Limit Theorem (CLT) apply to both measurements?

Suppose you believe that the true average daily trade volume for General Electric stock is 49,829,719 shares. Based on a recent sample you have also calculated a standard deviation of 21,059,637 shares. Considering a 95% confidence level, what is the minimum required sample size if you like your sampling error to be limited to 10,000,000 shares. What sample size would offer a sampling error of not more than 20,000,000 shares?

Given the information in item (5) above conduct a one-population test of hypothesis for the mean and determine if the null hypothesis should be rejected or not rejected.

Compare your findings in items (5) and (6) above and argue if you can make a generalization.

Is there a statistically significant difference between the average trading volume in 2017 and 2018? Hint: While technically, this can be carried out as a paired sample t-test since volume data are reported for the same stock, we will treat this as independent samples. Complete your calculations by hand assuming M2017=46108055, S2017=34099055, n2017=251, M2018= 87241844, S2018=50977722, n2018=238.

Repeat the test, this time by using SPSS. Hint: Create a new grouping variable for 2017 and 2018 and use it to run your test.

• Validate or refute your colleague’s evaluation of the juvenile justice policies.
• Expand upon your colleague’s conclusion(s) with your own research.
• Respond to Stuart as if you’re having a conversation with him. A few sentences and a question

The juvenile crime here in the United States has kept going up over the years. There are too many juveniles that’s incarceration, but it should be for the real evil crimes too. Just think if the court system would change the way the juvenile court system is today. Not all parents are going to know what their children are doing on a daily basis or even whom they are hanging out with them. By reading the news here lately and seeing all the types of crime juvenile committing is crazy. Some of the crimes that juvenile is committing these days are murder, robbery, drugs, school shooting, rape, and more types of crime. With all types of crimes that juvenile can get arrested for is broken down into three categories and they are as followed: Violent Crimes Index offenses, Property Crimes Index offenses, and other offenses ( www.ojjdp.gov, 2018).

These crimes are going on all over the United States. Males and females make these types of crimes, and it does not care what race you are either. With juvenile committing crimes these days it is up to the juvenile court if they are going to be tried as an adult. Yes, the court system is there to decide if it is going to stay in juvenile or go to adult court. Just think that the judge might not have all the facts in the case before he or she decides on what to do in the case against a juvenile.

In Tennessee Cyntoia Brown was only 16 years old whenever she was charged with first-degree murder. The Tennessee Supreme Court said Thursday that Cyntoia Brown, a Nashville woman serving a life sentence in prison for a murder she committed at 16, could be eligible for release after she serves 51 years in prison (Alund/Tamburin, 2018). The defense in front of the Tennessee Supreme Court like they did years ago brought in evidence of sex trafficking whenever Cyntoia Brown was 16 years old. Plus, her defense team was using the Supreme Court ruling in 2012 by giving anyone under the age of 18 years old living in prison without parole was cruel and unusual punishment (Alund/Tamburin, 2018).

It’s crazy for someone that feels her life is in danger because of being forced into sex trafficking. Yes, it is a crime whenever you murder someone but not if you are doing it in self-defense. How would you feel if you own child was forced into doing things they did not want to do or if they do not something terrible going to happen to them? Right now her case is on the governor desk for a decision for clemency.

If you look at policy on crimes committed by a juvenile it not that good. To me, you need to outline the different types of crime and things that can happen to you by committing those type of crime. If you do not have a good guideline to go off of whenever trying to sentence any juvenile for a crime. By having it already in writing it is going to be hard that juvenile says I did not know that this could happen to me. Also, you should hold parents reliable for their children’s action because it might make parents know what their children are doing whenever they are not at home.
