We will decide one-tailed or two-tailed on the basis of the alternative hypothesis, not on the basis of null hypothesis.

[@MetaEducationByShaliniMam]

both can be one tailed and two tailed, and called as directional hypothesis, either directional null hypothesis or directional alternative hypothesis.

[@armyman9907]

@@MetaEducationByShaliniMam yes both can be one tailed and two. But in most of the practical situations null hypothesis considered as the simple hypothesis and alternative as a composite hypothesis.

Mam please ye bataiye ki real jindagi me kis chiz me use karte hai

[@preetipilania7903]

When we do research of something...we use hypothesis before the research and these are the tentative ideas that will be apply to actual research.

[@MetaEducationByShaliniMam]

Yes

[@mirishfaq161]

iz the direction of differance known in advance in using 2 tailed test

[@MetaEducationByShaliniMam]

Yes

[@mirishfaq161]

Meta Education how mam

[@MetaEducationByShaliniMam]

If we are comparing mean scores of two groups and our null hypothesis is " there will be no significant difference between two groups". And if mean score of group A is higher than mean score of group B. Than before testing null hypothesis we can assume that if our null hypothesis be rejected than we can say that group A is higher than we have to subtract mean B from mean A and we also know that t score will come positive value.

[@MetaEducationByShaliniMam]

One more thing null hypotheses is a nondirectional hypothesis it just tells about that difference is exist or not. It does not tell about the direction.

[@arjunsinha8359]

Di ham level of significance max time 5% ya 1% per kyu cheak krte hain ....

Which of the following is an one tailed alternative hypothesis: a) alternative hypothesis is population mean less than 0 b) null hypothesis is population mean is equal to 0 c) Alternative hypothesis is population mean is not equal to 0 d)both a and c

[@MetaEducationByShaliniMam]

Thanks for asking this question... According to my knowledge option a should be correct.

[@aayushkumar7442]

@@MetaEducationByShaliniMam I also think that a is correct because in c) case it is no equal sign in alternative then in null hypothesis there must be equal sign and it means the rejection region will be on both side of normal distribution and it will be two tailed test..

[@MetaEducationByShaliniMam]

Yes u r right

[@loneayat1973]

Mam null hypothesis one tailed and 2 tailed both hota hai... Hum null hypothesis me mat kehta hai ki M1 is greater or less then M2.. Hum kehtay hai there is no difference between two

[@MetaEducationByShaliniMam]

again good question null hypothesis m ham NO, Not ko use karte hn .... Mean of experimental group is not lesser than or equals to control group.... it is the example of one tailed null hypothesis. i hope it will be helpful to u.

Because in one tail test the whole 5 % cases sift towards left or right side according to hypothesis.... And according to percentage of cases and covered area the 5% cases lie below the -1.645 and in case of positive one tail test 5%cases lie above +1.645 And and 1.96 is the value in twotail test

Good question Anju The critical region of the sampling distribution of a statistic is also known as the α region. It is the area, or areas, of the sampling distribution of a statistic that will lead to the rejection of the hypothesis tested when that hypothesis is true. Means wo region jnha true hypotheses ke reject hone ke chances hote hn
