A simple random sample from a population with a normal distribution of 105 body temperatures has x = 98.30 degrees F and s = 0.61 degrees F. Construct a 95% confidence interval estimate of the standard deviation of body temperature of all healthy humans. Is it safe to conclude that the population standard deviation is less than 1.10 degrees F? Is it safe to conclude that the population standard deviation is less than 1.10 degrees F?
A.This conclusion is safe because 1.10 degrees F is outside the confidence interval.
B.This conclusion is not safe because 1.10 degrees F is outside the confidence interval.
C. This conclusion is not safe because 1.10 degrees F is in the confidence interval.
D.This conclusion is safe because 1.10 degrees F is in the confidence interval.
