1. the hawker claims that the average weight of each Apple sold by him is 50 grams. Now, to understand whether the claim is true, we will carry out hypothesis test. (1) What should be the hypothesis of nihility and opposition?
(2) Set the significant level of 0.05, we decided to randomly select 100 apples for examination, so what is the selection of the test statistics（ Including use conditions and sampling distribution)
(3) Why reject domain?
(4) If the average weight of 100 apples randomly selected is 48.5g and the standard deviation is 7.5G, what is the statistical value of the verification?
(5) What are the results and conclusions of the verification?

Step-by-step explanation:
