Question

Stats help please?

Answer 1

total how many pennies are there in the table ?

Answer 2

336

Answer 3

doesn't look correct
you're looking at the bottom table where the ages are between 1 to 9, right ?

Answer 4

oh no i was looking at the top where it says the following chart gives the ages of 336 pennies drawn from current change

Answer 5

i think the question is referring to the bottom table

Answer 6

i got 239 adding up all the ones on the bottom under the ages

Answer 7

Yes!
whats the "mid" value of first 239 positive integers ?

Answer 8

239/2 = 119.5

the mid value is 120, so the median would be the "age" corresponding to the 120th penny

Answer 9

ohh ok so do i go to the bottom where all the pennies are listed and find the age that its in? because when i did that i got that the age was 2

Answer 10

Excellent! the median age is 2 for the bottom table
