The hypothesis being tested is:
H0: µ = 33
Ha: µ < 33
The p-value is 0.0004.
Since the p-value (0.0004) is less than the significance level (0.05), we can reject the null hypothesis.
Therefore, we can conclude that µ < 33.
The 92% confidence interval is between 23.349 and 29.718.
The 80% confidence interval is between 24.221 and 28.846.
