The September 14, 1999, issue of Soap Opera Digest consisted of 130 pages, including 28 pages with advertisements. a) b) What are the observational units in this study? For each magazine, treat this issue's pages as a sample from the population of all the magazine's pages over all issues, and construct a 95% condence interval for the population proportion of pages that contain ads. Write a sentence or two interpreting these intervals. (Be sure to relate your interpretation to the context.) Clearly explain what is meant by the phrase \"95% confidence" in this context. Does each interval contain the sample proportion of pages with ads? Explain Why the previous question is silly and did not require you to even look at the intervals
