heet 1. Find the following: (Show a correctly shaded & labeled graph, and give 3 decimal places.) a. The critical values associated with a 92% confidence interval for a population proportion. b. The critical values associated with a 95% confidence interval for a mean when n = 25. 2. In a recent survey, it was found that 24% of women in the U.S. will have had an abortion in their lifetime, with a 1.9 percent margin of error. (Source) State the confidence interval 3. A fisheries researcher wants to estimate the average weight of the striped bass living in a nearby lake. To do so, she will construct a 90% confidence interval, with a margin of error of 0.27 lbs. She knows from her studies that the weights of striped bass overall have a standard deviation of 3.92 lbs. So, how many fish is she going to need to (randomly, of course) catch and weigh to estimate the population mean weight? Show formula, substitution, and result.
