A simple random sample from a population with a normal distribution of 99 body temperatures has \( \overline{\mathrm{x}}=98.80^{\circ} \mathrm{F} \) and \( \mathrm{s}=0.65^{\circ} \mathrm{F} \). Construct a \( 95 \% \) confidence interval estimate of the standard deviation of body temperature of all healthy humans.
