| Consider the variable “Product Rating”. Construct a frequency distribution for this variable using the classes (0.5, 1]; (1, 1.5]; (1.5, 2]; (2, 2.5]; (2.5, 3]; (3, 3.5]; (3.5, 4]; (4, 4.5]; (4.5, 5] and make a percentage polygon of this variable. Select the correct percentage polygon corresponding to the frequency distribution. | Beskou die veranderlike “Produkgradering”. Stel ‘n frekwensieverdeling vir hierdie veranderlike op deur die klasse (0.5, 1]; (1, 1.5]; (1.5, 2]; (2, 2.5]; (2.5, 3]; (3, 3.5]; (3.5, 4]; (4, 4.5]; (4.5, 5] te gebruik en maak 'n persentasieveelhoek van die veranderlike. Selekteer die korrekte persentasieveelhoek wat met die frekwensieverdeling ooreenstem. |
