In a frequency table, the upper boundary of each class interval has a constant ratio to the lower boundary. Show that the geometric mean G may be expressed by the formula: log G = xo + fi (i-1), ~ where xo is the logarithm of the mid-value of the first interval and c is the logarithm of the ratio between upper and lower boundaries.
