Answer 7

I am one of the last people you want to help you with your math.

Answer 8

Any other topic I can do.

Answer 9

then why are you in mathematics?

Answer 10

It just says everyone that is online and not viewing a question. It doesn't apply to that subject, as far as I have seen.

Answer 11

I will give you a medal though, and wish you luck.

Answer 12

@Ultrilliam anything?

Answer 13

*sigh* one sec lemme tell the person I'm playing chess with BRB x'D

Answer 14

...

Answer 15

Mean means average, so lets find the average of the dataset,

first lets find how many people there are,
(4*6)+(2*6)=36

next lets add up everyone in both tables
(4*7)+(4*7.5)+(14*8)+(5*8.5)+(7*9)=x

now to make sure I count them all
4+4+14+5+7=34... Welp I missed some
Uh...

but basically you would go through that, then divide x by how many there are, in this case there are 36

so x/36=y


does that make sense?

Answer 16

so its 36

Answer 17

NO

Answer 18

Read what I posted

Answer 19

okay, so it is 36

Answer 20

i'm just pulling your legs man

Answer 21

Negative. That is part of the equation, not the answer

Answer 22

Oh thank heavens x.x

Answer 23

2.75 / 36

Answer 24

275 i meant

Answer 25

that seems more plausible, but I think your missing a few numbers, as I was, and I ended up with 275.5

Answer 26

7.652

Answer 27

I'm recount them all hang on

Answer 28

8+8.5+8+7.5+9+9+8+7+7+9+8+8+8+7+7+8+7.5+8.5+7.5+8+8.5+9+8+7.5+8+8+8.5+8+9+8+9+9+8.5+8=275.5

Answer 29

so 275.5/34?

I had it wrong, the second table only has 5 rows, so it would be
(4*6)+(2*5)=34

Answer 30

8.10

Answer 31

this is gonna be a long day...

Answer 32

Correct

Answer 33

now lets do this

Answer 34

@Ultrilliam

Answer 35

One sec

Answer 36

I feel like all of these are statistic... but I could be wrong

Answer 37

idk...

Answer 38

@Ultrilliam

Answer 39

ok I know this is closed but I got tagged in this while I was at work

for the first one they only want the sample mean of the bottom 10 numbers

Answer 40

the second one is a bit harder: parameter describes the entire population and statistic describes the sample

for the golf one I would say statistic since they imply they only sampled some golf teams
soccer team: the data spans the entire soccer team so I would say parameter
swim team: probably statistic since they only sampled 28 swim teams
basketball: this is kind of vague but I'd say parameter
