The most popular age group for passengers taking a cruise from an American port is 60-69 years of age. This group makes up 20 percent of all cruisers. Dolphin Cruise Lines wants to see if their 60 to 69-year-old passenger percent average is different than the entire cruise industry’s mean of 20 percent, which has a standard deviation of 4.4 percent. If they want a .01 level of confidence, design the hypothesis test. If Dolphin Cruise Lines samples 36 passengers and determines this sample mean is x̄ = 22 percent, decide to reject or do not reject the null hypothesis
