Question

A teacher asked each of his students how many books were read during the summer. Which histogram accurately displays this data?

Answer 1

Answer:

The histogram that accurately displays this data is:

                            Histogram A

Step-by-step explanation:

For a histogram we first divide the data into disjoint class intervals such that the width of the intervals is equal.

Here we divide the class interval as:

0-9 , 10-19 , 20-29 , 30-39 and 40-49

Also, on making a frequency table we may get the height of bars in the histogram corresponding to each class interval.

Class-Interval            Frequency

    0-9                                9

    10-19                              6

   20-29                             3

   30-39                             3

   40-49                             3      

This means that the height of the class interval 0-9 must be 9

10-19 must be 6

20-29 must be 3

30-39 must be 3

and 40-49 must be 3.

Answer 2

Answer:

The frequency distribution is given below:

Class                      Frequency

0 - 9                               9

10 - 19                             6

20 - 29                           3

30 - 39                           3

40 - 49                           3

From the given 4 options, the histogram in option A accurately displays this data. Hence the option A is correct.
