When studying the life-span (measured in years) of adults in comparison to the number of days they spend outdoors, what would be a reasonable value of the range (their life-span)? A:-2, B:5, C:150, D:75

52 cm radius = diameter = area = circumference = circumfer

(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.)

Find the dimensions of the circle. area = 64π in.² r= in.
