What sample size should be obtained if she wishes the estimate to be within 2 percentage points with 90% confidence, assuming the following? (a) She uses the estimates of 18.8% male and 20.5% female from the National Center for Health Statistics. (b) She does not use any prior estimates.According to a poll taken in a certain country, when adults were asked whether they were thriving, struggling, or suffering, 193 out of 440 said they were struggling. a. What is the value of p, the sample proportion that say they are struggling? b. Check the conditions to determine whether you can apply the CLT to find a confidence interval. c. Find a 95% confidence interval for the population proportion that say they are struggling.The state education commission wants to estimate the proportion of tenth-grade students that have reading skills at or below the eighth-grade level.

How many rolls must Julia make to get a margin of error less than or equal to .05? [To find n, use the guessed value p* = 1/6 for the sample proportion and the values for z* from a z-table or t-table.] [Round to the smallest integer that works.] n =A national media outlet conducted a poll which estimated that 82% of all voters believed global warming exists had a margin of error of +/-3%. Suppose an environmental grop planning a follow-up survey of voters' opinions on global warming wants to determine a 90% confidence interval with a margin of error of no more than +/-2%. How large a sample do they need? Use the media outlet's estimate as the basis for your calculation.
