Jared is reading a 300-page book he borrowed from the library. So far, he has read 85 pages. He has 5 more days to read the book before he returns it to the library. How many pages must he read on average per day in order to finish the book before he returns it to the library?

(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.)
