The distance (in km) of 40 engineers from their residence to their place of work were found as follows: 5 3 10 20 25 11 13 7 12 31 19 10 12 17 18 11 32 17 16 2 7 9 7 8 3 5 12 15 18 3 12 14 2 9 6 15 15 7 6 12 Construct a grouped frequency distribution table with class size 5 for the data given above taking the first interval as 0-5 (5 not included). What main features do you observe from this tabular representation?

The marks obtained (out of 20) by 30 students of a class in a test are as follows: 14, 16, 15, 11, 15, 14, 13, 16, 8, 10, 7, 11, 18, 15, 14, 19, 20, 7, 10, 13, 12, 14, 15, 13, 16, 17, 14, 11, 10, 20. Prepare a frequency distribution table for the above data using class intervals of equal width in which one class interval is 4-8 (excluding 8 and including 4).

If the average marks of 17 students in a class is A. The marks of the students when arranged in either an ascending or a descending order was found to be in arithmetic progression. The class teacher found that the students who were ranked 3rd, 7th, 8th, 11th, 15th had copied in the exam and hence got all of them rusticated. The average of the remainder of the class was B. Then

Level-3 11. On Vanmahotsva day, students of class IX were asked to get saplings & develop nursery in the triangular region allotted to them as in the figure given below: A 2 3 4 5 6 7 8 9 10 (i) Find the coordinates of the vertices P, Q, R (ii) Find the area in which the nursery has been developed

Tabulate , the given data by taking Class intervals : 1-10 , 11- 20 , 21- 30 , 31- 40 Data : 9 , 10 , 8 , 6 , 7 , 4 , 3 , 2, 16 , 28 , 22 , 36 , 24 , 18 , 27 , 35 , 19 , 29 , 23 , 34.

the daily minimum temperatures in degrees Celsius recorded in a certain Arctic region are as follows: -12. 5 ,-10. 8 ,-18. 6 ,-8. 4 ,-10. 8 ,-4. 2 ,-4. 8 ,-6. 7 ,-13. 2 , -11. 8 ,-2. 3 , 1.2 , 2.6 ,0,-2. 4 ,0, 3.2 , 2.7 , 3.4 ,0,-2. 4 ,-2. 4 ,0, 3. 2 , 2.7 , 3.4 ,0,-2. 4 ,-5. 8 ,-8. 9 ,-14 ,6,-12. 3 ,-11. 5 ,-7. 8 ,-2. 9 Represent them as frequency distribution table taking -19. 9\ to-15 as the first class interval.

Construct a frequency table with class-intervals 0-5 (5 not included) of the following marks obtained by a group of 30 students in an examination: 0,5,7,10,12,15,20,22,25,27,8,11,17,3,6,9,17,19,21, 29,31,35,37,40,42,45,49,4,50,16.

Given below are the ages of 40 people in a colony: {:(33,8,7,28,30,25,6,50,24,44),(56,32,27,21,17,62,58,16,14,19),(24,31,27,5,12,46,15,42,67,34),(4,21,10,40,20,50,48,63,9,21):} Taking class intervals 1-10, 11-20, 21-30, 31-40, 41-50, 51-60 and 61-70, we construct a frequency distribution table for th above data.
