students clothing: 19/50 or 0.38 or 38%
students electronics: 11/50 or 0.22 or 22%
students pet = 5/50 = 1/10 or 0.1 or 10%
students candy = 15/50 = 3/10 = 0.3 or 30%
1) Adding it up the number of students we have:
19 +11+ 5+15 =50
2) To find out the relative frequency, let's write a quotient between each category and the total number of students.
students clothing: 19/50 = 0.38
students electronics: 11/50 = 0.22
students pet = 5/50 = 1/10 = 0.1
students candy = 15/50 = 3/10 = 0.3
3) Hence the Relative frequency for all of these 4 categories are:
students clothing: 19/50 or 0.38 or 38%
students electronics: 11/50 or 0.22 or 22%
students pet = 5/50 = 1/10 or 0.1 or 10%
students candy = 15/50 = 3/10 = 0.3 or 30%
