6. Find the mode of the observations 17. 10, 13, 18, 22, 13, 26, 9, 13, 19.

7. Find the mode of the observations 25, 20, 16, 12, 20, 16, 19, 23, 31, 20, 11, 18, 16.

8. Find the mean, the median and the mode of the observations 24, 12, 15, 28, 15, 22, 17.

9. Some observations are arranged in the ascending order as 9, a +3, a +7, 20, 23 and 26. If the median of the data is 18.5, find the value of a. Also find the mean of the data.​

Answer 1

Answer:

4. 8

5. 26

6. 13

7. 20

8. mean = 19

median = 17

mode = 15

9. a = 10

 mean = 18

Answer 2

Step-by-step explanation:

4. 8

5. 7

6. 13

8. mean=sum of observations /total number of observations

mode=15

median =7

7. 20
