The local football team won the championship several years ago, and since then, ticket
prices have been increasing $4 per year. the year they won the championship, tickets were
$20. write an explicit formula for a sequence that will model ticket prices. what will the ticket
price be 10 years after that championship year?

(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.)
