Transcribed Image Text:A data set includes 106 body temperatures of healthy adult humans having a mean of 98.7 °F and a standard deviation of 0.66°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?
Click here to view a t distribution table.
Click here to view page 1 of the standard normal distribution table.
Click here to view page 2 of the standard normal distribution table.
What is the confidence interval estimate of the population mean μ?
°F<μ< °F
(Round to three decimal places as needed.)
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 higher than 98.6°F.
B. This suggests that the mean body temperature is lower than 98.6°F.
C. This suggests that the mean body temperature could very possibly be 98.6°F.
