Given:

Total number of students = 20

The marks of the students are 40, 22, 36, 27, 30, 12, 15, 20, 25, 31, 34, 36, 39, 41, 43, 48, 46, 36, 37 and 40.

To find:

The frequency distribution table with class size 10.

Solution:

We have, the marks of 20 students.

40, 22, 36, 27, 30, 12, 15, 20, 25, 31, 34, 36, 39, 41, 43, 48, 46, 36, 37, 40

Here,

Minimum value = 12

Maximum value = 48

We nee class intervals of size 10. So, the required class intervals are 10-20, 20-30, 30-40, 40-50. In these intervals, lower limit is excluded but the upper limit included.

The required frequency distribution table is

Class intervals      Marks                                                  Frequency

10-20                    12, 15                                                            2

20-30                   22, 27, 20, 25                                             4

30-40                   36, 30, 31, 34, 36, 39, 36, 37                      8

40-50                   40, 41, 43, 48, 46, 40                                  6

Total                                                                                        20

Therefore, the frequency distribution table is

Class intervals:      10-20        20-30        30-40         40-50         Total

Frequency      :          2                4                8                6                20

Which of the following is true of the data set represented by the box plot max at 35
Bezzdna [24]

Though the box plot is not given, the truth about the data set represented by the box plot is <u>removing</u> the outliers would not affect the median.

<h3>What is a box plot?</h3>

A box plot gives a graphical (rectangular) representation of statistical data based on the following five values: minimum, first quartile, median, third quartile, and maximum.

Essentially, a box plot has the following five data descriptions:

  • The leftmost whisker, showing the minimum value.
  • The rightmost whisker, showing the maximum value.
  • The leftmost line, showing the first quartile.
  • The middle line, showing the median or the second quartile.
  • The last line shows the third quartile.

Thus, the truth about the data set represented by the box plot is <u>removing</u> the outliers would not affect the median.

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as ed
Travka [436]
Suppose x books are produced by both methods.
Total cost for method 1 = 60346 + 10.5x
Total cost for method 2 = 18682 + 21x

Cost of method 1 = Cost of method 2
60346 + 10.5x = 18682 + 21x
60346 - 18682 = 21x - 10.5x
41664 = 10.5x
x = 41664/10.5
x = 3968

For 3968 books produced the cost by both methods will be the same.
