Range Rule of Thumb for Interpreting s The 20 brain volumes $(c{m}^{3})$ from Data Set 8 “IQ and Brain Size” in Appendix B have a mean of $1126.0\text{}c{m}^{3}$ and a standard deviation of $124.9\text{}c{m}^{3}$ . Use the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of $1440\text{}c{m}^{3}$ be significantly high?

Converting repeating decimal in base b to a fraction the same base

The repeating decimal .36666... in base 8 can be written in a fraction in base 8. I understand simple patterns such as 1/9 in base 10 is .1111.... so 1/7 in base 8 is .1111. But I'm not too sure how to convert this decimal in this base to the fraction in the same base.
