Question

This project is related to statistical inference about the difference between two population parameters and the analysis of variance. You need to formulate hypotheses testing and confidence estimation as you learned in class. Each group must collect data related to the topic of their choice. You should specify your parameter of interest and the claim, make the hypotheses, perform test calculations and estimation, and make a conclusion.

specify your parameter of interest and the claim, make the hypotheses, perform test calculations and estimation, and make a conclusion. The topic should be related to one of the following chapters: (Ch 13 Inference about comparing two populations, Ch 14 Analysis of variance) can you please suggest me a topic ?

These are the requirement of the report, please suggest a topic/ hypothesis that i could work on:

You must prepare a report summarizing the findings of the research project. Specifically, your report should consider the followings:

1. A discussion of what question/s you are interested in (the parameter of interest).

2. Description of your used data set: details about data source and the collection process. The sample size for each variable should be larger than 30 observation.

3. Provide descriptive statistics of each variable (mean, median, variance, standard deviation, maximum, minimum, ...etc.)

4. Include table(s) and graph(s). 5. Discussion of whether the required conditions are satisfied.

6. Analysis: test, estimation.

7. Results: provide inferences about the questions of interest and discussion.

8. Conclusion: provide brief conclusions about the results of your study and state policy implications if any.

Answer 1

Suggested Topic

You may be interested to know if the marks obtained by students in Statistics in your last semester depended on the Gender or not.

1. First Collect data using random sampling. Sample size should be more than 30 to make it large sample

2. Group them according to gender

3. Calculate all descriptive statistics as required in your project

4. You may formulate the following Hypothesis

[That means if the average marks of male students in the population is equal to average marks of female studens]

Against the alternative

5. Then construct the ANOVA table for single Factor (You may use Excel Data > Data Analysis > One way ANOVA)

6. Check the calculated F value with F Critical value

7. If F Calculated > F Critical . then reject the Null Hypothesis, else accept it
