Select the correct answer. Henry used these steps to solve an equation:
Step 1: -3(+ 2) = 5(3 - 7)
Step 2: -3r - 6 = 57 - 35
Step 3: -83 - 6 = -35
Step 4: -81 = -29
Step 5: 1 = 23
Between which two steps did Henry apply the distributive property?
steps 1 and 2
steps 2 and 3
O
steps 3 and 4
steps 4 and 5

(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.)
