you will propose a hypothesis test that will test a
claim that is of interest to you in the business world. Then
describe how you would gather a representative sample to test that
claim.
1. state the claim you wish to investigate in your own words.
2. write a null and alternative hypothesis.
3. describe how you will gather a representative sample to test
your claim.
4. state the type of test you would use for example,
TTest,1PropZTest, etc.
