It is assumed that the boiling temperature in degrees Celsius of a certain liquid is a var X -N (µ, (1, 2) ^2), with µ unknown. The boiling temperature of 16 samples of this liquid is measured. The average of the measurements obtained is 94.32.

Q1: Formulate hypotheses H0 and H1

Q2: Calculate the Z statistic

Q3: Can we say, at the 5% risk, that the average boiling temperature of the liquid is different from 95 degrees Celsius?
