Assignment detailsScenarioYou are a new graduate researcher at a social and psychological sciences research institute. You have been given a dataset based on a survey of Australian public service sector employees, and asked to analyse the data to answer several questions of interest that are presented here.DataFor the purpose of this report, you should use the same dataset as for Assignment – Part 1. You should already have saved your random sample of 1500 of the 4352 observations from the original data fileSTA10003_Assignment_Data.sav (SAV 65 KB)and you do not need to draw a new random sample.Data analysisFor the purpose of your report, you must use SPSS to draw a random sample of 1500 cases of the 4352 observations. You will conduct your analysis on this sample of 1500. You should ideally use the same 1500 cases you used for Assignment – Part 1. However, you can draw a new random sample of 1500 cases if you need to.For your assignment, you are required to complete the first three questions by producing the appropriate analyses and writing the relevant report for each question. You are also required to complete Question 4, which contains three short answer questions. The reports should follow the format of the model reports provided in the Additional resources section. For each of the first three questions requiring SPSS, you should include the relevant output (e.g. tables) immediately following your report.Questions and instructions for Assignment 2 – Part 2										Question										Description										Instructions												1							The variableTeamEngagementis a scale score (0 to 20) of how engaged an employee is with the team of colleagues they regularly work with, with higher values representing greater employee engagement with their team.Previous research indicates that Australian public service employees have an average ‘team engagement’ score of 14.5.

Assignment 2: Analysis of data – Part 2
	Question 1 – One-sample t-test
Questions 1. To test the “Team Engagement” variable that the average value is decreased from the previous results.
Solution: Here, this is a problem of one-sample t-test. Here, the phycologist believes that the average “team engagement” score is decreased due to changes made by the government. The team engagement score is calculated on a scale of 0 to 20 and previous results showed that the average score was 14.5. Thus, we have to test that the average “team engagement” score decreased from the value 14.5.
Thus, the hypotheses are given as follows:
 
The test is applied by the help of the SPSS software.
Here, the level of significance is not mentioned. So, we consider it by default as .
Here, from the output the total sample size is 1500. The mean of the team engagement score is 11.92. The standard deviation is 6.100 that is the scores differ from the mean by value of 6.100. Also, the standard error is 0.158
The test statistic value of the test is -16.398.
The value of degrees of freedom(df) is  i.e. 1499.
Here, the p-value of the test is 0. 
The hypothesis acceptance or rejection depends upon the p-value. If the p-value is less than the level of significance then we reject the null hypothesis otherwise we accept it. Here, the level of significance is 0.05 which is greater than the p-value. Thus, we reject the null hypothesis.
Conclusion: Here, the null hypothesis is rejected which means that the average team engagement score is not equal to 14.5. Hence,
