Question

Please Help! @Loser66 @Vandreigan @iPwnBunnies

Answer 1

With what you know about probabilities, which one makes the most sense for question 1?

Answer 2

C

Answer 3

The survey revealed that 20/50 liked fall, while only 6/50 liked winter. So, I probably wouldn't say that there is the same amount. That's quite a large difference within 50 data points!

Answer 4

D, i didnt read c carefully

Answer 5

I'd agree with D :)

Answer 6

yeh

Answer 7

For question 2, I'm not familiar with that graphing style. I need to find out exactly what it means (specifically, what the box represents. I get the impression that it represents some number of standard deviations, but I need to know for sure).

Stay with me. Hopefully this won't take but a moment.

Answer 8

So, you may want to get some clarification on this one, but I'd go with B.

The girls values show more variation, as illustrated by the larger range. However, they show a lower standard deviation (if you've covered this), as they are more focused around one region.

Answer 9

ok

Answer 10

The next one reads like they want you to list all possible combinations of heads and tails that can be made by tossing 4 coins at once.

Since you are tossing them all at once, you lose track of which quarter is which (order doesn't matter), so it's a bit easier than before.

4H
3H 1T
etc.


If they want you to keep track of each quarter, it would look like:

HHHH
HHHT
HHTH
HTHH
THHH

etc. through all the possible combinations.

Answer 11

ok

Answer 12

i got 10 combinations

Answer 13

Which way are you doing it? Either way, 10 shouldn't be your answer.

Answer 14

a list

Answer 15

what did you get

Answer 16

If order doesn't matter: 5
If order does matter: 16

Answer 17

ok

Answer 18

for 16 what would be the probability

Answer 19

of what?

All we've done is count the total number of combinations possible.

Answer 20

oh part b

Answer 21

So, how many different ways can the quarters fall to leave two heads and two tails?

Example: HHTT, HTHT, etc.

Answer 22

4

Answer 23

HHTT
HTHT
THHT
HTTH
THTH
TTHH

Answer 24

6 ways, with a total of 16 combinations. Which gives us what probability?

Answer 25

6 out of 16

Answer 26

Reduce it, and you have your answer :)

Answer 27

3/8

Answer 28

number 4

Answer 29

Hmm, some terminology that I'm not familiar with. One second.

Answer 30

ok

Answer 31

I can't find anything solid for that one. I've never heard of a "mean average distribution" before.

Answer 32

I'd suggest trying to get the attention of someone else to help you on what's left. Unfortunately, I have to go.

Best of luck to you!
