your class of 32 students is divided into fourths to create groups to answer a set of questions together then 1/4 of each group has to go to the front of the classroom and read off the group answers how many students go up to the classroom for each group?

15 point ! ~ see if you know the answer to both you!

(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.)

For a function f(x), a) if f(7) = 22 then f^-1(22) = b) f^-1(f(c)) =
