A blue whale is the largest marine mammal. A random sample of 10 blue whales had a mean lung capacity of 5,000 liters and a standard deviation of 600 liters. An oceanologist reports that the population mean lung capacity of blue whales is 4,800 liters. Based on this random sample, do you support this researcher's report? Find the value of the test statistic (round off to third decimal place). Assume normal population
