Extracted text: A simple random sample from a population with a normal distribution of 99 body temperatures has x= 98.90°F and s = 0.66°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 2.20°F?
