Myra owns a car service that charges a $5 flat rate and an additional $0.50 per mile. A: y = 0.5x + 5

B: y = 5x – 0.5

C: y=0.5x-5

D: y=5x+0.5

(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.)
