31-40 and 41-50, construct a frequency
distribution table
c. Use this table to estimate the mean.​

Answer 1

Range is highest value-lowest value

Step-by-step explanation:

Table can't be explained here

Answer 2

Answer:

marks in ascending order will be

9,15,16,18,18,19,20,24,24,26,27,28,28,29,30,30,32,33,34,34,35,35,36,36,40,42,42,42,43,45

range = 45-9=36

sigma fixi= 900

sigma fi = 30

mean = 900/30=30

hope it is helpful.

pls mark me as brainliest...
