Consider the triangle. which statement is true about the lengths of the sides? each side has a different length. two sides have the same length, which is less than the length of the third side. the three sides have the same length. the sum of the lengths of two sides is equal to the length of the third side.

(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.)
