Part I

Typically when researching a business or academic issue, you would ask a question about something and form a hypothesis. You would then collect the data and test it to see if the null hypothesis (no difference) is supported or refuted. Then you would present the findings.

Now, open and carefully examine the data on the STAT 211 Altimeter Error spreadsheet (XLSX).
Then, construct a hypothesis and address the following in a document.

Describe what you are comparing.
State your hypothesis in a sentence.
Indicate the appropriate t-test that you will use to evaluate your hypothesis.
State the alpha (α) level.
