Answer 2

@texaschic101

Answer 3

it is A. i can tell you why.
gimmie a sec

Answer 4

thanks!

Answer 5

standard deviation alterations or each option:
A) 13.26
B) 10.10
C) 11.00
D) 9.9
E) 9.25

Answer 6

dont you need to find the Variance to find the standard deviation??

Answer 7

false?

Answer 8

an easier way of estimating though would be to consider that the number we are looking for needs to be an outlier and must not effect the number of plot points in out data.
so the farthest value from the mean with the smallest amount of change to the data is it in a nutshell

Answer 9

and yes you can use variance to find standard deviation.

Answer 10

ill post the formula

Answer 11

nvm just know that the Standard deviation is the square root of the variance.

Answer 12

\[\sqrt{variance}\] =Standard Deviation

Answer 13

or \[Standard Deviation ^{2} =Variance\]

Answer 14

both can go back and forwards it depends n the info the problem gives you

Answer 15

yes, but to find the variance, you need to to make a chart and stuff...

Answer 16

is this false??

Answer 17

yep you can. or you can use a graphing calculator like we do in AP stat :D

Answer 18

ohh smart! how tho?

Answer 19

is it false?

Answer 20

sorry i answered another question somehwere else the sum must be zero yes . so true. ill give example.

Answer 21

Data set: 4,5,6
mean: 5
4-5= -1
5-5=0
6-5= 1

-1+0+1=0 !:D

Answer 22

so yeah. thats the answer to that one. :)

Answer 23

would this be 11^2? so 121??

Answer 24

Answer 25

ya?

Answer 26

Can anyone help me in the question i just posted?

Answer 27

Can anyone help me?

Answer 28

Answer 30

0

Answer 31

like i had to think for a minute then i realized oh yeah its not diving by n so it has no other choice lol

Answer 32

@Ellews who was that for?

Answer 33

It wasnt for me Cause its none of the options

Answer 34

Someone Help me With My Question :c

Answer 35

and its not sqaured so it cant be a deviation or variance so its just a simple expression :p

Answer 36

i can try @yika3040 :)

Answer 37

what? @Ellews , so what would this answer be?

Answer 38

THERE NOW I POSTED IT

Answer 39

zero is your answer @4sodapop

Answer 40

thank you @Ellews

Answer 41

but i still dont get how

Answer 42

okay so i can brake down the formula for you if you would like?

Answer 43

\[\sum_{i=1}^{n} (X i- X \bar")\]

Answer 44

ya

Answer 45

which problem are you doing

Answer 46

okay so the
-big "E" looking thing is called a sigma. it pretty much just means add
-n stands for how mnay numbers we have ina data set.EX: 1,2,3,6 n=4
-i= stands for what term number we began evaluating the sequence with. for EX: 1,2,3,6 but i=3 then when we find the sum, standar deviation, the mean, etc we start from the 3rd term. so 3+6=9. 9 would be the sum of our sequence.
-and last in the parenthesizes it pretty much is saying each number minus the mean

Answer 47

so the sum of all out numbers minus the mean is what the equation is pretty much saying :)

Answer 48

ok, is this true or false?

Answer 49

x with the line or "bar" over the top is the mean of a sample

Answer 50

im soo lost..

Answer 51

Interquatile Range= Quartile 1- Quartile 3

Answer 52

so you tell me :)

Answer 53

and remeber a five number summary includes: Minnimum, Quartile 1, the median, quartile 3, and the maximum

Answer 54

*remember

Answer 55

isnt it Q3-Q1?

Answer 56

ahh yes god sorry donig 3 things at once. Q3-Q1 is the IQR now knoeing the 5 number summary can you find it ?

Answer 57

hint: the answer is yes. yes you can.

Answer 58

what is it asking? i dont get it

Answer 59

can you "hint the answer" again please. AKA just tell me!!
