High-power experimental engines are being developed by the Stevens Motor Company for use in its new sports coupe. The engineers have calculated the maximum horsepower for the engine to be 590 HP. Twenty-five engines are randomly selected for horsepower testing. The sample has an average maximum HP of 580 with a standard deviation of 45 HP. Use the confidence interval approach to determine whether the data suggest that the average maximum HP for the experimental engine is significantly different from the maximum horsepower calculated by the engineers. Use a significance level of a = 0.01. Assume the population of the maximum horsepower of engines is normally distributed. Step 1 of 2: Calculate a confidence interval for the average maximum HP for the experimental engine. Round your answers to two decimal places. Answer Keypad Keyboard Shortcuts Tables

If the animal is in the meadows on one observation, then it is three times as likely to be in the meadows as the woods on the next observation.Assume that state 1 is being in the meadows and that state 2 is being in the woods.(1) Find the transition matrix for this Markov process.
