Question

The points earned on this assignment will be added to your homework/quiz Suppose a group of 4 children have a mean age of 116 years What will the mean age of these 4 children be 5 years from now? p1: Come up with 4 numbers that will give you an average of 11.6. Write your numbers down here. (1 point) Ste Step 2: Add 5 to the 4 numbers you wrote down in step 1 and calculate the mean. (1 point) Step 3: Have you seen the relationship between the mean in step 1 and the mean step 2? If you have, please answer the question below. ( 1 point) Suppose a group of 25 children have a mean age of 11.6 years What will the mean age of these 25 children be 5 years from now?

Explanation / Answer

1) N= 4, MEAN= 11.6 YEARS AND SUM= 11.6*4= 46.4 YEARS

X1=11.6

X2= 10

X3= 12

X4=13

STEP 2) X1'= 11.6+5= 16.6

X2'= 10+5= 15

X3'=12+5=17

X4'=13+5= 18

NEW MEAN= (16.6+15+17+18)/4 = 16.6

YES THERE IS RELATION BETWEEN MEAN 1 AND MEAN 2

THE MEAN AGE OF THESE 25 CHILDREN FROM NOW IS 16.6
