14. Total plasma volume is important in determining the required plasma component in blood replacement theory for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that sample of 61 male firefighters are tested and that they have a plasma volume sample mean of ml/kg (milliliters of plasma per kilogram body weight). Assume that ml/kg for the distribution of blood plasma. Find the margin of error for 98% confidence level of the population mean blood plasma volume in male firefighters. Round your answer to two decimal places. (Points: 5)

2.24 ml/kg
51.90 ml/kg
0.94 ml/kg
0.29 ml/kg
0.34 ml/kg

To find the margin of error for a confidence interval, you need to use the formula:

Margin of Error = Z * (Standard Deviation / √n),

where Z is the Z-score corresponding to the desired confidence level, Standard Deviation is the standard deviation of the sample, and n is the sample size.

In this case, the confidence level is 98%, which means we need to find the Z-score for a 98% confidence level. Since the confidence level is in the middle, we can find the Z-score using a Z-table or a statistical calculator. For a 98% confidence level, the Z-score is approximately 2.33.

The sample size, n, is given as 61.

The problem statement does not provide the standard deviation of the sample, so we cannot calculate the margin of error without that information.
