1. The problem asks us to draw three graphs using the data from Q6: (a) a Histogram, (b) a Frequency Polygon, and (c) an Ogive curve, and then estimate the median wage from the ogive. 2. Since no specific data from Q6 is given here, generally: - (a) A Histogram displays frequencies for wage intervals as bars. - (b) A Frequency Polygon connects midpoints of each wage class frequency with straight lines. - (c) An Ogive plots cumulative frequencies against upper class boundaries for a "less than" cumulative frequency curve. 3. To estimate the median wage graphically from the ogive: - Locate half the total frequency on the vertical cumulative frequency axis. - Draw a horizontal line from this point to intersect the ogive curve. - From the intersection, draw a vertical line down to the wage axis. - The wage value where this line meets the horizontal axis is the estimated median wage. 4. Without Q6 data, we cannot plot exact graphs, but the method to estimate median from the ogive is as above. Final answer: The median wage is estimated from the ogive by finding the wage corresponding to half the total cumulative frequency.
