A data set includes 103 body temperatures of healthy adult humans, with a mean of 98.1°F and a standard deviation of 0.56°F. Construct a 99% confidence interval estimate of the mean body temperature of all healthy humans. What does the sample suggest about the use of 98.6°F as the mean body temperature? What is the confidence interval estimate of the population mean μ? ___°F < μ < ___°F

Step 1
Given: - Sample mean (x̄) = 98.1°F - Standard deviation (σ) = 0.56°F - Sample size (n) = 103 - Confidence level = 99% - z-value for 99% confidence level (zα/2) = 2.576 Margin of error = zα/2 * (σ / √n) Margin of error = 2.576 * (0.56 / √103) Margin of error ≈ Show more…

A data set includes 106 body temperatures of healthy adult humans, with a mean of 98.7 degrees Fahrenheit (°F) and a standard deviation of 0.63 degrees Fahrenheit (°F). Construct a 99% confidence interval estimate of the mean body temperature of all healthy humans. What does the sample suggest about the use of 98.6 degrees Fahrenheit (°F) as the mean body temperature? What is the confidence interval estimate of the population mean μ? °F < μ < °F (Round to three decimal places as needed.)

A data set includes 110 body temperatures of healthy adult humans having a mean of 98.0°F and a standard deviation of 0.74°F. Construct a 99% confidence interval estimate of the mean body temperature of all healthy humans. What does the sample suggest about the use of 98.6°F as the mean body temperature? What is the confidence interval estimate of the population mean μ? ____°F< μ<_____°F (Round to three decimal places as needed.)

Construct the appropriate confidence interval. A simple random sample of size $n=40$ is drawn from a population. The sample mean is found to be $\bar{x}=120.5$ and the sample standard deviation is found to be $s=12.9 .$ Construct a $99 \%$ confidence interval about the population mean.
