### Calculating the Margin of Error for a Confidence Interval**Determine the margin of error for the confidence interval for the mean:**\[ 18 \pm 1.5 \]---### Input your AnswerThe margin of error is \[ \_\_\_] .---#### Explanation:In this case, the margin of error is represented by the value that follows the \( \pm \) symbol, which is 1.5. This signifies that the true mean lies within the range of 18 minus 1.5 to 18 plus 1.5.**Steps:**1. Identify the mean (here, it is 18).2. Identify the margin of error (here, it is 1.5).3. Enter the margin of error in the provided input box.---This content helps students understand how to determine and input the margin of error when dealing with confidence intervals in statistics. This fundamental concept is crucial for interpreting data ranges and making informed conclusions based on sample data.

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 50 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.20 ml/kg for the distribution of blood plasma.
