Practicum Example 3: Statistical Inference I
Let us return to the importance of weather in some business decisions, especially for businesses that rely on public participation. Let us, therefore, return to our weather dataset to answer our two research questions.
Research Question 1: What is the probability of rain falling on July 4?
Research Question 2: What will the high temperature be for July 4?
Collecting the Data
The data for this journal activity is, as expected, weatherData.xlsx.
Analyzing the Data
Use the data to correctly answer the two research questions.
Interpreting the Results
Interpret your analysis. Include appropriate graphics.
Make sure that you defend your choices in your analysis. Be explicit about what statistical procedures you ran and why you ran those procedures. Your reader should never have to guess about your analysis.
Note that if you provide a point estimate, you will also need to provide a confidence interval for that estimate. If you use only part of the data, you will need to specify which part you used and why you only used that part. Defend your decisions.
Do the above before looking at the solutions. Jumping straight to the solutions provides almost no help for you. The benefit from practice is actually doing the practice. Do not cheat yourself.
