Solution
Here, we observe that, all 34 students have socred marks more than or equal to 0. Since, 32 students have scored marks more than or equal to 10. So, 34 - 32 = 2 students lies in the interval 0-10 and so on.
Hence, the frequency distribution table.
Class intervalNumber of students0−1034−32=210−2032−30=220−3030−27=330−4027−23=440−5023−17=650−6017−11=660−7011−6=570−806−4=280−904
Hence, the frequency distribution table.
