The area of the rectangular living room in your house can be modeled by a = 6x +11x
living room in your house can be modeled by a = 6x2 + 11x +3. if the value of x-5, what are the
dimensions of the width and length of this living room?

(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.)
