Question
The image shows a text problem focused on statistical analysis, specifically about finding a confidence interval for a population mean. Here's a transcription suitable for an educational website: --- **Plasma Volume Analysis** 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 40 male firefighters is tested and that they have a plasma volume sample mean of \( x = 37.5 \, \text{ml/kg} \) (milliliters plasma per kilogram body weight). Assume that \( \sigma = 7.10 \, \text{ml/kg} \) for the distribution of blood plasma. *When finding a 99% confidence interval, what is the critical value for the confidence level? (Give your answer to two decimal places.)* \( Z_c = \) **(a)** Find a 99% confidence interval for the population mean blood plasma volume in male firefighters. What is the margin of error? (Round your answers to two decimal places.) - Lower limit - Upper limit - Margin of error **(b)** What conditions are necessary for your calculations? (Select all that apply.) - \( n \) is large - The distribution of volumes is normal - \( \sigma \) is unknown - The distribution of volumes is uniform - \( \sigma \) is known **(c)** Interpret your results in the context of this problem. - We are 99% confident that the true average blood plasma volume in male firefighters falls within this interval. - We are 1% confident that the true average blood plasma volume in male firefighters falls within this interval. - The probability that this interval contains the true average blood plasma volume in male firefighters is 0.99. - The probability that this interval contains the true average blood plasma volume in male firefighters is 0.01. **(d)** Which equation is used to find the sample size \( n \) for estimating \( \mu \) when \( \sigma \) is known? - \( n = \left( \frac{Z_c E}{\sigma} \right)^2 \) --- This content would help students understand the statistical methods involved in analyzing blood plasma volumes using a confidence interval approach.
