Thousands of sailors get lost or have their boats sink on the world's oceans each year and utilize emergency communications to request rescue. An international maritime organization that collects data on these accidents and rescues gives the average response time to these emergency calls as 10 hours, with a standard deviation of 8 hours. (Al large standard deviation reflects the difficulty of reaching people on the vast Pacific and Southern oceans.) Internet technology has improved the situation for mariners needing rescue, and Elon Musk's STARLINK system has made rescues more likely because many mariners have access to Starlink and related apps - and therefore see distress calls that may be within reach of their location. In 2022, STARLINK extended its service over the Pacific ocean. A sample of 45 ocean rescues in 2022 yielded an average response time of 9.3 hours. Answer the following questions that requite analysis of this information. 1. What is the sampling distribution for this analysis? 2. Based on this information given, what is the expected value of the mean of the sampling distribution? 3. What is the standard error of the sampling distribution? 4. If your sample of 45 ocean rescues has an average response time of 9 hours, what is the Z-score that represents the location of this value in the sampling distribution? 5. What is the probability of getting this result (9 hours) or greater? (Enter as a percentage and if your percentage is less than one full percent enter a zero before the decimal point)
