Which shows three ordered pairs that are all solutions of the equation y = x +7. a. (0,7), (2,9), and (3,11) b. (0,7), (2,9), and (3,10) c. (1,7), (2,9), and (3,10) d. (1,8), (2,9), and (3,11)

(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.)
