1. How do I find/know Statistical Concerns
2. How would I conduct the project research to test the Hypothesis? (from Data Collection to Analysis)... 5 steps of Hypothesis Testing?

In the following scenario:

Examining of household bills in Year 2021 and Year 2020 to test the hypothesis on increase of consumption in Year 2021.

• Data is given Y2021: Number of households and bill of each household. So in Microsoft Excel, we can analyze the data using the 'descriptive analysis' analysis tool to get the following: Mean, Standard Error, Median, Mode, Standard Deviation, Sample Variance, Kurtosis, Skewness, Range, Minimum, Maximum, Sum, Count
• Data is NOT given for Y2020: Scenario only provided Mean and Standard Deviation for Y2020.
