Answer:

Since class isn't uniform,we must make it uniform.

For that, subtract .5 from lower class and add .5 to upper class.

So table is going to be this:

   Class                       Frequency                      Cf

199.5-219.5                        5                                 5

219.5-239.5                       8                                  13

239.5-259.5                       12                                 25

259.5-279.5                        10                                  35

279.5-299.5                          17                                52

299.5-319.5                           18                                 70

                            TOTAL:      70

half of 70 is 35

Therefore, median class is 279.5-299.5      

Im sorry cuz the numbers are not in line...and I hope it helps you...
