Question
According to an airport, only 50% of people arrive at least as early as the airport recommends for domestic flights A researcher wanted to check if this is true so he took a random sample of 50 people taking domestic flights and found that 30 of the people arrived at least as early as the airport recommends. At the 1% significance level, can you conclude that the current proportion is different than what the airport claims. What is the test statistic? O Test statistic = Test statistic Test statistic = 0.5-0.6 (0.5)(0.5) 50 50-30 30 √50 Test statistic = 0.6-0.5 (0.5)(0.5) 50 30-50 30 √50
