23. The specifications of a ramp for a motorcycle daredevil to complete a jump state that the slope of the ramp must be no steeper than 1.0 and no less than 0.6. If the ramp is 30 feet long and 19 feet tall, does the
ramp's slope meet the specifications?
19 ft
30 ft

(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.)
