Question 1182727: A data set includes 108 body temperatures of healthy adult humans having a mean of 98.3°F and a standard deviation of 0.69°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 does this suggest about the use of 98.6F 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 higher than 98.6°F.
C. This suggests that the mean body temperature is significantly lower than 98.6°F.

The confidence interval is .
From the data given,

= [98.13, 98.47].
98.6 degrees F is outside this interval on the right side, and so the answer is
C. This suggests that the mean body temperature is significantly lower than 98.6°F.
