A data set includes 103 body temperatures of healthy adult humans for which x̄ = 98.5 °F and s = 0.61 °F. Complete parts (a) and (b) below. a. What is the best point estimate of the mean body temperature of all healthy humans? The best point estimate is ____ °F. (integer or a decimal.) b. Using the sample statistics, construct a 99% confidence interval estimate of the mean body temperature of all healthy humans. Do the confidence interval limits contain 98.6 °F? 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.) Do the confidence interval limits contain 98.6 °F? a) No b) Yes What does this suggest about the use of 98.6 °F as the mean body temperature? A. This suggests that the mean body temperature could be lower than 98.6 °F. B. This suggests that the mean body temperature could be higher than 98.6 °F. C. This suggests that the mean body temperature could very possibly be 98.6 °F.

A data set includes 110 body temperatures of healthy adult humans, with a mean of 98.1°F and a standard deviation of 0.64°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? What should replace the question marks? Round to three decimal places. ?°F < μ < ?°F What does this suggest about the use of 98.6°F as the mean body temperature? Which letter is correct? A. This suggests that the mean body temperature could very possibly be 98.6°F. B. This suggests that the mean body temperature could be higher than 98.6°F. C. This suggests that the mean body temperature could be lower than 98.6°F.

A data set includes 110 body temperatures of healthy adult humans, with 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 What does this suggest about the use of 98.6°F as the mean body temperature? A. This suggests that the mean body temperature is significantly lower than 98.6°F. B. This suggests that the mean body temperature could very possibly be 98.6°F. C. This suggests that the mean body temperature is significantly higher than 98.6°F.
Use the technology of your choice to determine and interpret the range and sample standard deviation for those data sets to which those concepts apply. If those concepts don't apply, explain why. Note: If an exercise contains more than one data set, perform the aforementioned tasks for each data set. A study by researchers at the University of Maryland addressed the question of whether the mean body temperature of humans is $98.6^{\circ} \mathrm{F}$. The results of the study by P. Mackowiak et al. appeared in the article "A Critical Appraisal of $98.6^{\circ} \mathrm{F}$, the Upper limit of the Normal Body Temperature, and Other Legacies of Carl Reinhold August Wunderlich" (Journal of the American Medical Association, Vol. 268, pp. $1578-1580$ ). Among other data, the researchers obtained the body temperatures of 93 healthy humans, as provided on the WeissStats CD.
