A function is graphed below. Which function is best represented by this graph?
y= -(x + 1)² + 4
y=h2² - 4x + 3
+3
y= -2? + 40 +3
y= -(0 - 1)² + 4

(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.)
