Question 2
The marks (out of 10) obtained by 28 students in a mathematics test are listed as below:
8, 1, 2, 6, 5, 5, 5, 0, 1, 9, 7, 8, 0, 5, 8, 3, 0, 8, 10, 10, 3, 4, 8, 7, 8, 9, 2, 0 The number of students who obtained marks more than or equal to 5, is
(a) 13 (b) 15 (c) 16 (d) 17
In order to deduce any information from the given data, we will arrange the given data in a table, using tally marks.We use the repetitions to construct a tally table as shown below.The number 1 is represented as I. The number 2 is represented as II and so on. But number 5 is represented as
Table with tally marks from the given information is shown below
The number of students who obtained marks more than or equal to 5 = 4 +1 +2+6+2+2 = 17.
