watched so many videos on this by other people but it was only when you said the sentence at 6:56 that it finally clicked haha cant thank you enough

Fantastic. I had got my head around the normal dist but was totally confused with the binomial. I have just wasted hours of thinking when 5 mins of listening to you has explained it brilliantly.

what is the other method you can use for hypothesis test?

isnt it supposed to be a rejection in the upper tail if its greater than alpha (significance value)

@uncritisizerble 7 жыл бұрын

yes

@Alex-nk4pk 5 жыл бұрын

no because if it's greater than alpha (at either tail) it means there is a higher chance of that outcome happening. If it had a higher chance of happening then why would you wouldn't reject the null hypothesis, but accept it as true

Can you use z table for questions like these?

Just finished my A2 stats test. There was a hypothesis testing binomial question I'm not sure about. If for example, probability of during something is 1/4 and the tester thinks it's greater than 1/4. He did 10tests and got it 6times. Test at 1% significance level. Do I do P(X>6) or P(X>=6)?

@ExamSolutions_Maths 5 жыл бұрын

Ho: p=1/4 , H1: p>1/4. Reject Ho if P(X>=6) < 1%

Can someone explain to me why we are using a 1 tailed test instead of a 2 tailed test, surely if we wanted to look at both ends then we would use a two-tailed one instead and half the significance level or am I missing something? thanks. great video though!

@Ben-Thirkill 5 жыл бұрын

Since the hypothesis is that it is biased AGAINST getting a six, it is one-tailed, if, for example, we were testing to see if rolling six was bias at all, it would be two-tailed as we are testing to see if there is a bias for either getting six or not getting six.

@SteveSmith-tt3rg 11 жыл бұрын

You will definitely lose point by saying accept H0. Instead you should say fail to reject H1, and there is not sufficient statistical evidence at 0.05 significance level (95% confidence level) to support the statement that the dice is NOT fair

formulate hypotheses and carry out a hypothesis test concerning the population mean in cases where the population is normally distributed with known variance or where a large sample is used.make a tutorial on this asap
