Question

the table below shows the number of hours high school students of different cities of two states spend on outdoor activities each week:

State A: 17 3 15 12 14 21 18 3 16
State B: 14 12 10 13 15 14 12 15 11

Part A: Why is the histogram for State A different in shape, center, and spread than the histogram for state B?
Part B: In which state did the students spend more average time on outdoor activities? Justify your answer.

Answer 2

For A... they ask for "Why". Well to be honest, that is just the nature of the data you obtained. You happened to get data that was quite different than for state B, so you can't be guaranteed that you'll get the same spread, center and histogram shape.

Answer 3

For B. I would consider taking the average for each state. Like for state A, add up all the values and divide by 9 (the number of data values you have)

And for state B, do the same procedure. Add up all the values and divide by 9.

You should then compare which state has a higher average number

Answer 4

oh ok thank you so much much ^-^ but if i may ask what exactly do i say for part A??

Answer 5

Well, it's again just the nature that you have a different data set in A then in B. In A, it looks like you have two outliers, the value "3". (Though they may not entirely be outliers). This kind of has the effect of "stretching" your histogram to the left. You could argue maybe that the data is different since it reflects different habits of people living in different states?

Answer 6

oh ok thank you sorry if i respond late i have horrible connection but thank you ^-^. ok so for Part B: you dont mind we could work on that together do you?

Answer 7

ok

Answer 8

so first what do i need to do??

Answer 9

Add up all the individual numbers in state A

Answer 10

17 + 3 + 15 + ...

Answer 11

ok i got 238

Answer 12

just add up the the ones belonging in state A

Answer 13

I think you added the ones in state B as well

Answer 14

oh opps sorry i did sorry im really dislexec but i got "119"

Answer 15

yeah 119 looks good :)

Answer 16

now since there are 9 values in state A, just divide 119 by 9.

Answer 17

ok i got 13.2 oh and sorry for the long responce

Answer 18

yeah that's good

Answer 19

JUst do the same procedure for state B (add all the values and divide by 9)
Then, just compare the value you obtained for state A and B. Then, the largest value represents the state, who on average, spent more time on outdooor activities

Answer 20

oh ok got it i got 116 then i divided it and got 12.8

Answer 21

yup. :) So you can say State A did more outdoor activities since 13.2 > 12.8

Answer 22

Thank you so so so much you were a really big help ^-^
