A Jesus Christ lizard is jumping across the water in search of food. The equation h= -12t^2 + 6t models the lizard's height in feet above the water t seconds after he jumps. 1. how long after jumping is he back on the water?
2. how high is each jump?
3. how long does it take to get to his highest point?​

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 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 σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
