Suppose the line of best fit for some data points has a slope of 1.885. If the
mean of the x-coordinates of the data points is 3.448, and the mean of the y-
coordinates is 12.318, what is the y-intercept of the line to three decimal
places?

(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.)
