Step-by-step explanation:
The mean is calculated as
mean =
Set 1
sum = (2 × 27) + (2 × 28) + (3 × 29) + (2 × 30) + (1 × 33)
= 54 + 56 + 87 + 60 + 33 = 290
The count is 10 ( number of dots ), then
mean = = 29
Set 2
sum = (4 × 24) + (4 × 25) + (2 × 27)
= 96 + 100 + 54 = 250
The count is 10 ( number of dots ), then
mean = = 25
