A survey was made to Portuguese youtubers about the number of times they made live videos during the month of January. With the data obtained, the following table was constructed:

Number of videos 0 1 2 3 4 6 10 15 Total
Number of youtubers 320 200 109 A 30 30 B 23 C
Youtubers percentage 40 D E F G H 3 I J

1.1 Determine the values of A, B, C, D, E, F, G, H, I and J.
1.2 Calculate the average, mode and standard deviation of the number of youtubers that
made live videos. Study the asymmetry of the frequency distribution.

EDIT:
It is identical with the exercise provided by the teacher.
I dont have more information about the exercise.
Don't know what to do!

Thanks!
