Question

Find the confidence level and alpha for a 92 % confident interval What is the confident level? (Type an integer or a decimal) Suppose that you have obtained data by taking a random sample from a population that you intend to find a confident interval for the population mean mu. Which confidence level, 95% or 99%, will result in the confidence interval giving a more accurate estimate of mu? Explain your answer. A confidence interval for a population mean has length 22. A. Determine the margin of error. B. If the sample mean is 50, obtain the confidence interval C. Construct a graph that illustrates your results. A sample mean, sample size, population standard deviation, and confidence level are provided. Use the information to complete below. x bar = 33, n = 25, confidence level = 90% A. Use the one-mean z-interval procedure to find a confidence interval for the mean the population from which the sample was draw. The confidence interval is from to 8. Obtain the margin of error by taking half the length of the confidence interval. What is the length of the confidence interval?

Explanation / Answer

4. Confidence interval is the probability of finding something in that interval with that probability.

So here confidence interval is 0.92

And alpha is 1-0.92, so here alpha is 0.08
