Answer

  1. (a) 15
Explanation:

The point where two ogive curves intersect gives us the median value on X - axis.
  1. (d) All of the above.
  1. (a) Histogram
  1. (b) 35
Explanation:

Mode value is located on X - axis at the intersection point of two adjacent bars alongside the highest bar.
  1. (d) None of the above
Explanation:

Mean cannot be located graphically, so the value of mean is indeterminate in this case.
