Acandle is 10 in. tall after burning for 2 hours. after 3 hours, it is 8 1/2 in. tall. a. write a linear equation to model the height h of the candle after burning t hours. b. predict how tall the candle will be after burning 6 hours.

(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.)
