Answer 2

Answer:

The new mean is 24.

Step-by-step explanation:

The property of arithmetic mean states that when a number is subtracted from all the observations, then the new mean will also get subtracted by the same number.

Therefore new mean = 30-6 =24.

Mean = 30

Total numbers = 10

Total sum = 10×30 =300

If 6 is decreased from all numbers

that means, Mean subtracting(10*6) from 300

Total sum =300-60 =240

New mean = $\frac{240}{10} =24$

Hence new Mean = 24.
