I am having an issue with the following task: For the dose of the MemPro medicine it is known that has normal distribution. Sample of 30 parameters has been taken into consideration and based on the obtained data, we know that mean of a dose of this medicine is 5grams. With possibility that alpha error is 5%, test the hypothesis that mathematical expectation is 6grams.
Could you please elaborate this, I have no idea how to solve this matter. Thanks in advance.
