A group of adult males has foot lengths with a mean of \( 27.18 \mathrm{~cm} \) and a standard deviation of \( 1.34 \mathrm{~cm} \). Use the range rule of thumb for identifying significant values to identify the limits separating values that are significantly low or significantly high. Is the adult male foot length of \( 30.4 \mathrm{~cm} \) significantly low or significantly high? Explain.
