Can you use these results and Theorem 12.2 (see image) to test the nullhypothesis that ? = 150 thousand miles against the alternative hypothesis ? < 150 thousand miles at the 0.01 level of significance for the following: the times to failure of a power train component in a certain car make and model are (in thousands of miles) 225, 459, 54, 180, 585, 558, 36, 342, 270, 378, 108, 396, 18, 252,135, 18, 162, 297, 171, and 27. Consider these data to be a random sample from an exponential (?) population.
FOR THIS, WE REJECT THE NULL FOR BOTH MODELS.

My lawn needs mowing , but i do not want to mow if its going to start raining while I'm in the middle of the job. So i am looking at the sky evaluating the weather, using the null hypothesis: "It will rain within the next two hours". In this situation , what would a type I error be?
