hello friends this video statistics part
24th is brought you by exam feel calm no
more fear from exam before watching this
video please make sure that you have
watched statistics part 1/2 pound 23
there are double that made of 5
observation is 0.4 that is n is equal to
5 that is the first thing and the mean
is 0.4 that this mean is 0.4 and the
variance is 8.2 from that this variance
is 8 point correct III of this
observation are 1 to 6 and find the
matter of the wishes to efficiently
define let the table we should be XY
then the total set will be 1 to 6 X N
and for the set N is going to f----- I
mean is equal to 4 point 4 and variances
variance is 8 point so we can say that
let's find the mean mean is going to 1
plus 2 plus 6 plus X plus y my 5 and
this that is nothing but 4 quite good or
we can say that X plus y is nothing but
4 point 4 into 5 0.4 into PI 5 a
25-minute we do 9 because 6 plus 2 8 + 1
9 that is 30 so we have got our first
equation X plus y is equal to now second
equation says the beta is equal to eight
point two four so various we know is
nothing but 1 by n Sigma X I - mean
square correct so we had known that or
we can say that Sigma X I - mean square
is nothing but and into variance n is
equal to nothing but 5 and variance is
eight point two four eight point two
point and that comes out to be 40 one
point
that is nice second official correct now
let's expand this is an X I is equal to
1 so this becomes 1 minus mean is
nothing but 4 point 1 right 1 minus 4
point pushback plus second matters 2
minus 4.2 Schneider right value is 6 6
minus 0.25 plus X minus 4 point 4
squared plus y minus 0.2 span is equal
to 41 point this equation we have if you
solve this equation what you'll get this
turns out to be 1 minus four point four
that is three point minus three point
four square plus 2 minus 4 point 4 is
minus two point four five plus six minus
four point four is nothing but one point
six square plus X minus four point
coastal X square plus four point four
square minus 2 into wait till 4 point 2
into X plus y square plus four point
four square minus 24 into 4 point 4 into
y is equal to 41 or minus three point
four squares but to eleven point five
six plus two point four square is
nothing but five point seven six plus
one point six squares but to two point
five six plus X square plus 0.4 square
is nothing but nineteen point three six
minus eight point eight X plus y square
Plus again 4.4 squares a day per day
with 26 minus eight point eight five
isn't it 41 or what we get is X square
plus y square minus 8 point 8 into X
plus y values plus you add everything
this side this is the Cooper be eight
point six zero this is equal to 41 point
X plus y we know is nothing but thirteen
here in this equation it specifies 30 so
you put this s 30 so what we get here is
X square plus y square is nothing but 41
point 2 plus 8 point 8 into 14 minus 58
miles if you solve this this comes out
to be this is 8 0.8 into cutting is
nothing but one hundred fourteen point
four so if you just add this this and
this becomes this becomes nothing
matters 1e five six - 58.6 and this
becomes actually 90 so this might till
now what we have got we have got X plus
y is equal to 30 and X square plus y
square
thank you let's square this equation
space Phi this becomes X square plus y
square plus 2x times X plus y is
personal to expert plus y square plus 2
X square is equal to 30 square this 160
by X square plus y square I can mention
97 degrees or we can say X Y is equal to
169 minus 97 and this is comfort to me
v6 knows this comes out to be 72
actually nine minus seven is two sixty
minutes or insanity or we can see that
XY is nothing but DV 6 so we have proper
equation so we have a row XY now we have
a look expertness y square and he ever
makes
so we can say that X square plus y
square minus 2xy
this has nothing but 97 minus 2xy 70
great we saw - ability that is nothing
but dy so we can see that X minus y
whole square because this whole thing is
X plus y squared you know 25 or thus if
you can say that X minus y is nothing
but plus management either 5 1 minus 5
so we have two equation one is X minus y
is equal to five and here X plus or the
X minus y is equal to minus then another
equation we have X plus y split that we
already have so let's say X plus y is
equal to 30 that is valid and go the
case you solve this okay we'll add this
two we get 2x is equal to DP always say
X - 9 and she is X good tonight we did Y
is equal to nothing but X minus 5 that
is y is equal to Y is equal to X minus 5
so 9 minus 5 is equal to in this case
and even add this this becomes 2x is
equal to 14 13 minus 5 that is 8 so X
here what do you get my Y is nothing but
X plus 5 at least 4 plus 5 minutes
so XY is either poor thing when I do is
find the same thing that we speak and
tell that the other two terms are over n
all right so the whole city is nothing
but 1 to 6 what we have done we have
this found equation at x and y and we
have solved the question says that in
each of the observation that is x1 x2 x3
is increased by a anything is plus a
plus a plus a then a is a negative or
positive number
the variance in history let's find the
earlier variance is 1 by n into X I -
mean formation of this summation of this
right now
then assume the Y is nothing but X pi +
T because we are adding with quantity e
they'll find the mean of Y I mean over
is the third summation of Y that is
summation of pi I by n correct so this
becomes nothing but summation of cy x i
plus summation of e by n that is nothing
but Sigma X I by n plus n into n this
cancel this is nothing but X pi or x
mean + right so what we have got is my
mean is nothing but X mean takes me Plus
this is my question
now let's find our variance the variance
2 is nothing but 1 by n here instead of
x + ik by summation of Y I - y mean
square current now instead of Y I or LC
all right why is nothing but X mean plus
it's me
- this is why this is why I mean sorry
this is my question why is a different X
I plus B this X I plus let me return to
you why are you gonna put X I plus C
that is summation of X Phi plus a - my
name is why I mean my mean is nothing
but X B plus a X mean loves correct this
whole summation by here Easy's cancel so
what we get is nothing but 1 by n into
summation of X Phi minus x mean X P
Square C square and this is nothing but
my variance 1 square this variance for
again through that very
yes one is equal to variance T correct
and that's what it very separate we have
done yet this as you why is meant to
make Cyprus a we found why be that came
out to be X B plus a and then the first
various was 1 by n summation of X I
minus X mean square and the second
summation is 1 by n into y minus y mean
square we found that Buddha thank you

that is three point minus three point
four square plus 2 minus 4 point 4 is

six square plus X minus four point
coastal X square plus four point four
square minus 2 into wait till 4 point 2
into X plus y square plus four point
four square minus 24 into 4 point 4 into
y is equal to 41 or minus three point
four squares but to eleven point five
six plus two point four square is
nothing but five point seven six plus
one point six squares but to two point
five six plus X square plus 0.4 square
is nothing but nineteen point three six
minus eight point eight X plus y square

it's me
