Obtain a statistical study in specific site above . This study should have results that shows continuous data. For the data, make sure you look on the link above and it cannot be something that is paired by a statistical analysis.

*Note, please show your work in each step including computation on calculator, histograms and how you reach to your answers include data points (snip the place you retrieve the data from the site above and show your work). Answer all propmpts presented with (-)

-Make an introduction on what your study you choose and include if experiment or observational study is given.

-Contain an explanation as to why you are interested in the topic you chose and why you are want to study that topic

-Contain a statement about what you think the results of your experiment/observation will be. "This statement should include a numerical value you would expect to get in general from taking the average of a population". You will need to either find a population mean from online data or approximate this at the start of the study. This value is what will be used for our null hypothesis, so it needs to be selected before you begin collecting data and analyzing the sample mean later.

Secondly

-Describe the type of study you are conducting. Meaning is it experimental or observational? Explain your reasoning.

-Describe the experimental or observational study design you are using. This description should include appropriate vocabulary that was discussed when learning about experimental and observational study designs.

-Describe the sampling strategy you used. This description should include appropriate vocabulary that was discussed when learning about sampling designs.

Contain an explanation as to how you plan to obtain your data.

-Collect at least 20 data values. If you collect less than 30, can you technically assume your data is normally distributed? Explain.

-Determine if your data is normally distributed by creating a histogram. Show this histogram and describe it's distribution.

-If you collected more than 30 data values, can you still use a normal distribution to assess/analyze your study? Explain why or not using statistical knowledge

-Even if your data is not normally distributed and your sample size is less than 30, you will still complete the project as if it were. However, this may be something to address in your conclusion.

Finally

-Calculate the mean of your data. Would this be considered the sample mean or population mean? Why? present your mean in sentence form, putting it in context.

-Calculate the standard deviation of your data. Would this be considered the sample standard deviation or population deviation? Why? What is the meaning of the standard deviation you computed?

-Calculate a confidence interval (you choose the percentage) around the population mean you originally selected. Can this confidence interval be used to estimate where the mean of a sample may fall? Explain your reasoning.

-Refer to the estimate you made for the population mean above.

-Based on your data, do you think the population mean would be more than, less than, or just different than the sample mean? Is this statistically significant? Explain with calculations and numerical reasoning. Note that a hypothesis test must be conducted .

Analyze your own statistical data and method of conducting your study. Was there any bias present? If so, describe the type of bias and possible steps you could have taken to avoid this bias. If you were to perform this study again, would you change anything about your methods? Were there any flaws in your methods or results?

Describes the results you obtained and any statistical significance found. Were these results surprising or interesting to you? Did the result reflect what you had expected, or were they different. What suggestions would you make based on your results? Would you feel confident sharing as truth to other people based on your study? If there isn't anything you found to be significant or trustworthy enough to share confidentially, explain why
