Suppose you have a box with a very large number of orange and blue beads. You want to estimate the proportion p of orange beads in the box and you want to be 94% confident that your point estimate, which is the sample proportion p̂ , is within 6% of the true proportion p. Find the appropriate sample size.
The appropriate sample size is n= ____________

QUESTION PART A: You want to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable estimate for the population proportion. You would like to be 90% confident that you esimate is within 0.5% of the true population proportion. How large of a sample size is required? n = Do not round mid-calculation. However, use a critical value accurate to three decimal places. QUESTION PART B: You want to obtain a sample to...
please don't round mid calculation(:
· Question 16 You want to obtain a sample to estimate a population proportion. At this point in time, you have no for the population proportion. You would like to be 90% confident that you esimate is within 0.05 of the true population proportion. How large of a sample size is required? Do not round mid-calculation. A group of researchers is interested in middle school students and their willingness to appear to stand out. A...
You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately p*=19%p*=19%. You would like to be 98% confident that you estimate is within 4% of the true population proportion. How large of a sample size is required? n =
You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately p 0.35. You would like to be 96% confident that your esimate is within 2% of the true population proportion. How large of a sample size is required? Hint: Shouldn't the answer be a WHOLE NUMBER n=2390.171
You want to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable estimate for the population proportion. You would like to be 99% confident that your esimate is within 1% of the true population proportion. How large of a sample size is required? n =
You want to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable preliminary estimation for the population proportion. You would like to be 99% confident that you estimate is within 3% of the true population proportion. How large of a sample size is required? n =
a. Assume that a sample is used to estimate a population proportion p. Find the 95% confidence interval for a sample of size 198 with 42 successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. 95% C.I. = b. A political candidate has asked you to conduct a poll to determine what percentage of people support her. If the candidate only wants a 0.5% margin of error at a 99% confidence...
