The table below shows the relationship between the approximate number of hours and the corresponding number of days on Saturn. Saturn Hours Days 266 and two-thirds 25 373 and one-third 35 426 and two-thirds 40 586 and two-thirds 55 What is the approximate number of hours in 72 days on Saturn? 603 and two-thirds 658 and two-thirds 743 768

(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.)
