I WILL MARK Maria just got a raise at work. She was making $9 per hour, but now she makes 150% of that amount.

Explain how you would find the amount of money Maria now makes per hour.

DO NOT PUT THE SAMPLE RESPONS (ik I misspelt that lol)

(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.)
