Find the z-score corresponding to the given value and use the z-score to determine whether the value is unusual. Consider a score to be unusual if its z-score is less than -2.00 or greater than 2.00. Round the z-score to the nearest tenth if necessary. A body temperature of 99.6° F given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°.
