I’m trying to study for my Statistics course and I need some help to understand this question.

Project 2 Questions

Hypothesis Testing (use Stat Crunch) – 

1. Write the null hypothesis and the alternate hypothesis in words.
2. Write the claim in statistical notation:
   1. H0: ?=  (null hypothesis)
   2. H1: ?<     or     H1: ?>     or     H1: ??    (alternate hypothesis)
3. Test your claim with 90% confidence. What is the significance level (alpha – ?)?
4. What is the test statistic? (round to 2 decimals)
5. What is the p-value? (round to 2 decimals)
6. Interpret the p-value?
7. Compare the p-value to alpha, and decide whether to reject or not reject.  Write this out in full sentence for example: “I reject ___ and have enough evidence to support ___”.
8. Explain what a Type I Error would be in your particular case.
9. Summarize any highlights from your exploration of data.  Summarize your intent, your findings and anything you learned.  Did you prove your claim or did you find out that you were wrong?  Did you have to change your original claim because you didn’t find the best data that represented your inquiry?
