The mean, variance, β_1 and β_2 of a distribution are 10,15,1 and 3. Find the four moments about origin.

Determine the relationship of ab and cd given the following points

If f(x) = 6x – 4, what is f(x) when x = 8? a2 b16 c44 d52

(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.)
