A math coach collected categorical data from 136 students about practice day and confidence rating. Counts: practiced on a weekday and reported high confidence = 22; practiced on a weekday and reported low confidence = 21; practiced on a weekend and reported high confidence = 54; practiced on a weekend and reported low confidence = 39. Total = 136. In a column-relative-frequency table, what entry should appear in the row labeled practiced on a weekday and column labeled reported low confidence?
