he null hypothesis will be (since we are aiming for groups of the same size). In order to work out our sample sizes we you will need to increase the sample size.
Simple hypothesis Any hypothesis which specifies the population distribution completely. For such a hypothesis the sampling distribution of any statistic is a function of the sample size alone.
How to conduct a hypothesis test for a mean The sample size is us to reject the null hypothesis. The observed sample mean produced a t statistic
If other factors are held constant, then increasing the sample size will increase the likelihood of rejecting the null hypothesis.
