*Chapter 6, Section 1-CI, Exercise 011 Use the normal distribution to find a confidence interval for a proportion p given the relevant sample results. Give the best point estimate for p, the margin of error, and the confidence interval. Assume the results come from a random sample. A 99% confidence interval for p given that p = 0.36 and n = 500. Round your answer for the best point estimate to two decimal places, and your answers for the margin...
- Your answer is partially correct. Use a t-distribution to find a confidence interval for the difference in means M, = # - My using the relevant sample results from paired data. Assume the results come from random samples from populations that are approximately normally distributed, and that differences are computed using d = 11 - 12 A 95% confidence interval for using the paired difference sample results. = 3.7.84 = 1.9.14 = 30. Give the best estimate for the...
