When conducting a statistical analysis, confidence intervals provide a range of values within which the actual value of a population parameter is likely to fall. For the standing height of U.S. males, a data sample has been taken, and the resulting 95% confidence interval has a lower limit of 5 feet 4 inches and an upper limit of 6 feet 4 inches.
The range within the 95% confidence interval can be determined by calculating the difference between the upper and lower limits. In this case, the range within the 95% confidence interval for the standing height of U.S. males is 12 inches or 1 foot. This means we can be 95% confident that the actual population means the height of U.S. males falls within this range.
The error term is another essential statistical concept representing the degree of error that may occur due to random chance or sampling variation. It can be calculated using the formula: (Upper limit - Lower limit) ...
