2. Since the interval does not include 32, hence you can reject the null hypothesis and there is enough evidence to conclude that the actual mean flight time of all balloons differ from the advertised 32 hours.
<h3>What are the hypothesis tested?</h3>At the null hypothesis, it is tested if the mean flight time is of 32 minutes, that is:
At the alternative hypothesis, it is tested if it differs of 32 minutes, hence:
The confidence interval is of (28.5, 31.4), that is, is does not include 32, hence you can reject the null hypothesis and there is enough evidence to conclude that the actual mean flight time of all balloons differ from the advertised 32 hours.
