Extracted text: ems: 1. Answer the following concept questions in 1-3 sentences each. (a) Is a sample mean likely to be exactly equal to the population mean? Explain why or why not. (b) Will the sample mean (or sample proportion) always be inside a confidence interval for the population mean (or the population proportion)? Explain why or why not. (c) Suppose you have one dataset. You create two different confidence intervals from it, a 92.6% confidence interval, and a 96.2% confidence interval. Which interval will be wider? (d) Setup: You obtain a dataset from a random sample. • You double-checked your dataset, and there were no typos, and no errors. • All conditions were met to develop a confidence interval. • You develop a 94% confidence interval for the population proportion p, and your confi- dence interval is 0.465 <>< 0.685.="" •="" you="" double-checked="" your="" calculations,="" and="" everything="" was="" done="" correctly.="" 0.39.="" why="" question:="" later,="" you="" find="" out="" that="" the="" actual="" population="" proportion="" is="" p="" doesn't="" your="" confidence="" interval="" contain="" the="" actual="" population="" proportion?="" (e)="" explain="" why="" you="" might="" want="" to="" potentially="" use="" the="" formula="" n=""> instead of n > 4h2 pô (1 – p) h2 for the population proportion. In the formula, h represents the amount of error you are willing to accept, and p represents the sample proportion. when calculating the sample size required when finding a confidence interval
