Question

In Chapter 7 of Devore, we learned about two-sided confidence intervals as well as one- sided confidence bounds. In this week's Chapter 8 reading, we're learning about the various forms that Null and Alternative hypotheses can take, and how they can be viewed as relating to each other. Describe your intuitive sense of how the ways we discussed confidence intervals and bounds will be helpful when testing hypotheses of the types and relationships covered in the text. Discuss how you are starting to see (or not, if you still feel that way) statistics being connected to the kinds of real-world problems you expect to encounter as an engineer. Response Guideline Post your response of 1-3 paragraphs (about 100-200 words) by the due date for this discussion assignment, and then reply to at least two initial responses of your peers during the remainder of the week, particularly focusing on responses that might differ from your own. Also respond appropriately to anyone who posts questions against your own postings. Discuss the content! Keep responses focused on the substance of the issue, not simply on agreeing with a comment or encouraging each other.

Explanation / Answer

Confidence interval is a range of values that is likely to contain an unknown population parameter. If you draw a random sample many times, a certain percentage of the confidence intervals will contain the population mean. This percentage is the confidence level. Most frequently, you’ll use confidence intervals to bound the mean or standard deviation. Confidence intervals is equal to acepted region for two sided hypothesis testing. For one sided hypothesis also it hapened.
