Henry predicted whether he got answers right or wrong in his 50 question exam. He identified the 36 questions he thought he got right.
It turns out that Henry got 5 questions wrong that he thought he got correct and he only got 11 of the questions wrong he had predicted.
What is the percentage accuracy he had with predicting his scores?

(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.)
