This is Prof. Jay Mistry Prof. Of statistics. Wonderful and amazing explanation. Keep it up.😇

jaymistry

Thank you Mam for Wonderful Explanations .

The question u solved is two tailed. significance level for two tailed test is 0.025 (0.05/2) not 0.05

hiraawan

Ans : Mean = 4.5
S.D. = 1.5
Z = 2
So, H0 is Rejected .

JayPatel-uzfy

Normal distribution
R=1.5
Mean=4.5
S d=1.5
Z=2

Z≤1.96 then our Z=2 ..so HO is rejected..

Binomial distribution...
n=9
R=1
P(r≤ro)>0.05
Ans= p(r≤ro) =0.01953=0.02
Then HO is rejected...

Is it correct mam ??!

janvinasit

In finding z value ...there should be minus sign but you write positive sign kindly explain this mam

nadiabatool

Memm binomial method is answer is 0.003 and normal method is answer is -2 right yaa wrong answer

GODZ_____HE

Whichever is less positive or negative is considered r right ?

Ma'am sign test for two samples video chahaya please

Withme

Thank you mam your explanation is very well 🤗

sushmitavimal

Mam Z<1.96 So our null hypothesis accepted . where we take median 2.6, n=9, mean 4.5, sd1.5 and R 2.5 and Z 1.66 so H not accepted

nashirhussain.

Thank you so much... it's really needed for sem 6 tybcom exam

pruthvivasoya

Mam why we have decided negative signs i.e. 2 as not positive?

pranjalghone

The table you derived was wrong there is no value as 12 in question you must have mistakenly taken 12 in place of 15 please re check it

Z ki value to negative m.arahi h ?? Then uska kea bnega mam plzz

sajidmahmood

Hello mam can u give me the solution of that question u have given in home work

shreyajha

Hello Mam....
Second Example
Normal distribution H0 is accepted
Binomial distribution H0 is rejected

dhruvdesai

Madam you took mean as n/2 but mean is something different, like add values and then divide by Numbers. Kindly explain this. Secondly how did you take s S. D? What's it's General formula? By the way your method of teaching is best, I like it

darakhan

Some teachers use directly t pstv t netv and t minm.
