Answer 1

Answer:

The new mean is 225

Step-by-step explanation:

Average = sum of observations/ No of observations

We are given that The mean of 100 numbers is 112.5

112.5 = Sum of 100 numbers / 100

112.5 × 100= sum of 100 numbers

11250 = sum of 100 numbers

Each number is multiplied by 2

so , Average = 2 ( sum of 100 observations) / 100

Average= 2 ( 11250) /100

Average = 225

Hence the new mean is 225
