QUESTION 2 (1 POINT) We want to carry out a quality control of the wine that our company is going to sell. To do this, 7 bottles are opened and we taste their content. The quality is scored with a value between o to 5 (o poor, 5 excellent). The wine is considered to be of acceptable quality if the average quality is greater than or equal to 3.

a) (0,5 points) List and explain the steps you will take to perform this test: steps, tables consulted, calculations to be performed, etc. The question does NOT ask for the results of the calculations, but for the procedure, step by step, that you will carry out.

b) (0,5 points) & What does the error of this calculation depend on? Indicate which parameters increase or decrease the margin of error.
