For samples of the specified size from the population described, find the mean and standard deviation of the sample mean x-bar. The mean and the standard deviation of the sampled population are, respectively, 182.1 and 29.4. n = 36 μx-bar = 29.4 and σx-bar = 4.9 μx-bar = 356.9 and σx-bar = 1.0 μx-bar = 182.1 and σx-bar = 4.9 μx-bar = 4.9 and σx-bar = 182.1

Question 2 (1 point) Suppose you take a sample of size 4 from a population with a mean of 70 and a standard deviation of 10. Based on such a sample, what are the mean and standard deviation of the sampling distribution of the sample mean? Question 2 options: 70; 5 17.5; 10 70; 2.5 17.5; 5 Cannot be determined if sample size is not at least 30

Confidence Level Question 1 One hundred random samples, each of size 25, are obtained from the Normal distribution with mean 0 and standard deviation 1 using Minitab. Subsequently, the 1-Sample Z procedure in Minitab is used (with the same confidence level) to obtain a confidence interval from each sample. Out of the 100 intervals thus obtained, 89 include the number 0. Estimate the confidence level (in percentage terms) used to generate the 100 intervals using a 95% confidence interval. a....
