Hi guys, I am trying to solve this problem but honestly I am quite stuck, can anyone help me ?
By taking several measurements I get these normally distributed values: 20.6-20.9-20.1-20.2-21.8-21.1.
First point ) Tests the hypothesis that the measurement comes from a process with a mean of 20.4.
Second Point) Find the 95% confidence interval for the true value of the measurement.
