In Katya’s car, the number of miles driven is proportional to the number of gallons of gas used. Find the missing value in the table. (at the bottom) a. Write an equation that will relate the number of miles driven to the number of gallons of gas.

(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.)
