Answer 1

Answer:

I don't know

Explanation:

you have to read in ur school or collage

Answer 2

Answer:

use the formula of assumed mean for discrete series which is A + Sigma FD / Sigma F then assume the assumed mean to be 60 then find out D which is X- Assumed Mean then multiply the values of D with the frequencies which is the number of plants then take out FD and sum them up which is sigma FD hence the final answer which you will get should be 62.16
