An inventor has developed a new, energy- efficient lawn mower engine. He claims that the engine will run continuously for more than 5 hours (300 minutes) on a single gallon of regular gasoline. The inventor selects a simple random sample of engines from his stock for testing. He wants to test the null hypothesis /: ( = 300 against the alternative hypothesis Ha: u > 300. He uses a significance level of 0.01. The test returns a P-value of 0.02
