I need help with the case study below. Specifically which online calculator is the most appropriate as well as help with the questions below. Thank you in advance for your help!
Summarize the results in a paragraph or two. Include summary statistics.
Which statistical test is the best to use, why?
What is the null and alternative hypotheses that were tested or what is the claim?
Are there any observed difference between the variances / standard deviations of the data sets? What is the practical significance of that difference?
What does this outcome tell us about efforts to date to slow the spread of the virus and flatten the curve? Working? Not working? A work in progress yet?
Include a copy or screenshot of the software or calculator output to support the write-up.
Measuring if the Curve has Flattened
Use a computer program such as Excel or other computerized statistics software or an online calculator to calculate the statistical significance of the difference between the following mean daily infection rates. There are links to online calculators in the Resources section below.
