Quite often we can find the critical value for a given test and also this can be used an alternative method of testing a hypothesis


 
Hypothesis testing - Finding an Upper Critical Value for the Binomial Distribution
In this example you are required to work out the upper critical value for a Binomial Distribution. A particular drug has a 1 in 4 chance of curing a certain disease. A new drug is developed to cure the disease. How many people would need to be cured in a sample of 20 if the new drug was to be deemed more successful at curing the disease than the old drug to obtain a significant result at the 5% level?
