Answer 1

Answer:

Median = 95 .

Step-by-step explanation:

We are given with the following data below;

   Marks obtained               No. of students (f)       Cumulative Frequency (cf)

           92                                       14                                     14

           95                                       15                                     29

           98                                        6                                     35

          100                                        5                                     40

                                                ∑f = 40  

Now, First we calculate $\frac{N}{2}$  ,where N = ∑f ,i.e. $\frac{40}{2}$ = 20 .

Here, the cumulative frequency(cf) just greater than or equal to 20 is 29.  

Therefore, marks of student corresponding to cf 29 is 95.

Hence median marks of students is 95 .
