According to a flyer created by BroadwayPartyRental.com, their 18-inch helium balloons fly, on average, for 32 hours. You purchase a SRS of 50 18-inch helium balloons from this company and record how long they fly. You would like to know if the actual mean flight time of all balloons differs from the advertised 32 hours. a) State an appropriate pair of hypotheses for a significance test in this setting. Be sure to define the parameter of interest. b) b) A 95% confidence interval for the mean flight time (in hours) for all helium balloons is (28.5, 31.4). Based on this interval, what conclusion would you make for a test of the hypotheses in #1 at the α = 0.05 significance level?
