Jlvesh is analyzing the flight of a few of his model rockets with various equations. In each equation, h is
the height of the rocket in centimeters, and the rocket was fired from the ground at timet = 0, where t is
measured in seconds.
Jivesh also has a more powerful Model B rocket. For this rocket, he uses the equation h=-90t4 + 300t.
When is the height of the Model B rocket 250 centimeters? Round your answers to the nearest
hundredth.
After t =
seconds, the rocket will have reached a height of 250 centimeters.

(b) suppose that consolidated power decides to use a level of significance of ฮฑ = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is xโฏโฏ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume ฯ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
