A 50% confidence level has a confidence interval of 0.6745. A 90% confidence level has a confidence interval of 1.96. A 99% confidence level has a confidence interval of 2.57. A critical distance is measured 17 times. The mean is 317.6 feet, the sample standard deviation is 0.46 feet. The standard error of the mean value with a confidence level of 90% is (A) (2.57) (0.46) 17 (B) (1.96) (0.46) 17 D. (1.96) (0.46) V17 (D) (0.46) (17) 1.96
The confidence level in a confidence interval is established by A Z-value, such as 1.96 for a 95% confidence interval A t-value, using the appropriate degrees of freedom and the level desired The appropriate statistic for the test distribution The F statistic, using the appropriate degrees of freedom and the level desired
