Solution

Dear Student Thank you for using Chegg !! Given blood type of 25 students a) Complete frequency table Solution :- Computed using [ %Contribution * N Of Students i.e. % X 25] Blood Grp. % Frequency AB 16 4 AB 20 5 B 28 7 O 36 9 b) Size of Central Angle 100% corresponds to 360 Degree in pie chart => 1% Corresponds to 3.6 Degree in pie chart Blood Grp. % Size of Central Angle AB 16 57.6 AB 20 72 B 28 100.8 O 36 129.6 Total 360 c) Mode of Given data set In the given data set since blood group O has maximum frequency so it should be Mode
