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?

What is the confidence interval estimate of the population mean u? O°F
Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!

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 very possibly be 98.6°F.
B. This suggests that the mean body temperature is significantly lower than 98.6°F.
O C. This suggests that the mean body temperature is significantly higher than 98.6°F.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F66ac5d0d-fc89-4c09-8186-ee5bac8ff70c%2F3c10ffe5-91da-45a8-ae74-a98deb1143cb%2F11kf21_processed.png&w=3840&q=75)
