Question

help

Answer 1

@satellite73

Answer 2

can u help me add steps

Answer 3

i have no idea what a median median line is
do you?

Answer 4

Sort the collected data by the independent variable.
Divide the sorted data into three groups.
Find the median x and the median y of each group.
Find the equation of the line that passes through (x1, y1) and (x3, y3).

Answer 5

first is your answer right?

Answer 6

we can to through it if you like, it will take a while (not too long)

Answer 7

....

Answer 8

No i just need the steps that make sense

Answer 9

ok we need to sort the data in to three groups of four from smallest to largest

Answer 10

\[150,301\\
210,540\\
790,508\\
812,587\] is the first group of 4 unless i made a mistake

Answer 11

the median of the x values (first numbers) is 500
the median of the y values (second numbers) is 524 we need those two numbers
clear, or no?

Answer 12

yea

Answer 13

but how is what i put on the question?

Answer 14

we are not even close to done
you can put that though

Answer 15

what we are doing is finding the equation of the line
where did you get \[y=.35x+252\] from? that is what we are trying to find

Answer 16

idk google

Answer 17

all the work is finding that line
that should come first

Answer 18

first you should have "sort the data\[

Answer 19

\[150,301\\
210,540\\
790,508\\
812,587\]

Answer 20

then you should have "the median of the x's is 500 and the median of the y's is 524

Answer 21

now we have to do the same with the highest group

Answer 22

can just give me the steps cuz i dont got all day

Answer 23

jeez what do you think i am doing?????

Answer 24

sorry, continue

Answer 25

largest group is \[3214,817\\
3578,1647\\
7742,3013\\
7810,3619\]

Answer 26

median of the x's is 5660

Answer 27

median of the y's is 2330

Answer 28

the equation of the line through \[(500,524), (5660,2330)\] is \[y=.35x+349\] so unless i made a mistake your answer is wrong

Answer 29

where did you get the \(252\) out at the end?

Answer 30

google

Answer 31

well who knows, i used wolfram to get the line, maybe i made a mistake earlier on, but it seems unlikely we would both get the same slope by coincidence

Answer 32

can i jut erase everything I put there

Answer 33

you can copy down what i wrote
the last part would be \[y=.35x+349\] then \[y=.35\times 1950+349=1031.50\]

Answer 34

Thank you

Answer 35

you're welcome, you can check my work if you like, maybe i made a mistake
do you have the google link?

Answer 36

nope

Answer 37

good?

Answer 38

your ordering is all messed up

Answer 39

lol...

Answer 40

fix it.

Answer 41

the median of the x values (first numbers) is 500 the median of the y values (second numbers) is 524 we need those two numbers

y=.35x+349
then
y=.35×1950+349=1031.50

Sort the collected data by the independent variable
. Divide the sorted data into three groups.
Find the median x and the median y of each group
. Find the equation of the line that passes through (x1, y1) and (x3, y3).
150,301
210,540
790,508
812,587
largest group is
3214,817
3578,1647
7742,3013
7810,3619
median of the x's is 5660
median of the y's is 2330

Answer 42

first the instructions

Answer 43

Sort the collected data by the independent variable . Divide the sorted data into three groups. Find the median x and the median y of each group . Find the equation of the line that passes through (x1, y1) and (x3, y3).

Answer 44

150,301
210,540
790,508
812,587
the median of the x's is 500, the median of the y's is 524

Answer 45

largest group is
3214,817
3578,1647
7742,3013
7810,3619
the median of the x's is 5660 median of the y's is 2330

Answer 46

the equation of the line through \((500,524)\) and \((5660,2300)\) is \[y=.35x+349\]

Answer 47

if \(x=1950\) then \[y=.35\times 1950+349=1031.50\][

Answer 48

done

Answer 49

much better~
hope it is right...

Answer 50

me too

Answer 51

i couldnt finish this one

Answer 52

if you have the google link that gave you the other answer i will look at it

Answer 53

lol nice art work

Answer 54

Thanks!

Answer 55

but good enough i guess,
should look like your frequency table turned sideways

Answer 56

now that is art!!

Answer 57

Settle down

Answer 58

did you find the mean and the median?

Answer 59

dosnt look like it, we need to do c, and d

Answer 60

how are you going to find the relation between the mean and the median if you don't know it?

Answer 61

the things i do for you
http://www.wolframalpha.com/input/?i=mean+%7B17,16,56,50,14,30,12,33,82,16,10,52,25,25,19,75,24,12,30,12,20,38,26,36,33,24,18,26,40,40%7D

Answer 63

i would say "the data looks skewed to the left.
the median is 25.5 but the mean is larger, 30.37

Answer 64

lolllll

Answer 65

it does not look like a normal distribution because is is skewed left
normal would look like

Answer 66

instead of like

Answer 67

"it is" skewed left
and get rid of "normal looks less curved" that does't make any sense

Answer 68

rude

Answer 69

moi?

Answer 70

im leaving that last part

Answer 71

fine if you like it, leave it

Answer 72

anything else to add?

Answer 73

hows this

Answer 74

honestly you are on your own with that one, i really really know nothing about boxes and whiskers

Answer 75

kk all good, wanna do more?

Answer 76

more than anything

Answer 77

is it more of this, or something easier to deal with ?

Answer 78

umm

Answer 79
