WILL MARK BRAINLIEST a. After the first 1/8 hours of installing the fence posts, you have used 1/4 of the posts. What is the unit rate you are installing fence posts per hour?
b. Write an equation that represents the relationship between the number of fence posts used, y, in hours.

(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.)
