Answer 1

Answer: Graph Attached

Step-by-step explanation:

From given

Less than type               CF         Class interval       Frequency

Less than 5                      2                  0-5                        2

Less than 10                    8                   5-10                       6

Less than 15                    18                  10-15                     10

Less than 20                   27                 15-20                     9

Less than 25                    35                20-25                    8

Hence , the less than curve is in the attached graph
