In Chapter 7 of Devore, we learned about two-sided confidence intervals as well as one-sided confidence bounds. In this unit’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 should be 1-3 paragraphs (about 100-200 words)
