(i) 10, 20, 30, 40​

Answer 1

Answer:

mean is 10+20+30+40÷4 is 100÷4=25

Answer 2

Answer:

25 is the mean.

Step-by-step explanation:

Since this is just raw data we use the same formula for finding mean as we use for finding average.

Sum of values of observation divided by number of observations.

Sum of values of observations = 10+20+30+40=100

Total number of observations = 4

100 divided by 4 gives 25.
