Find the rule if the Y values in the table are 2.5, 4, 5.5, and 7?
Notice that the Y-Values increase by ___, so the rule includes___x. To obtain the correct value for X=1, You must add ___. So, the rule is Y= ___ X+ ___. Test the rule when X= 1. Does the rule work? ___

(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.)
